Religion vs Science
It is a common meme, especially among those who believe in one or more gods (hereafter referred to as believers) that science "has it in" for religion, that the scientific establishment is actively opposing the religious establishment or its beliefs. This idea is completely false. Many scientists are believers and no scientific journal has ever published a paper attacking religion. No scientist has claimed that he can prove that God exists or does not exist. God's existence remains completely unverifiable (by either school of thought), and therefore by definition it is not a subject for science. If you define religion (or just your faith) as a belief in God, then science has no opinion on the matter.
However, if your faith depends on (or even includes) the literal truth of the Bible, Koran, Torah, Bhagavad-Gita or any of the thousands of other allegedly sacred writings (hereafter referred to as the Bible), then science can and does conflict with your religious beliefs. Again, no scientific paper attacks these beliefs directly. For example, I have never seen a paper in a peer-reviewed journal that said "Genesis never happened." Science isn't concerned with the Bible, so it doesn't address it, much less attack it.
Long ago, before the age of science and reason (and even later for Mormons and Moonies), people had no way to understand the world around them. Everything was inexplicable. What are the stars, sun, moon, and planets, and why do they move as they do? What causes thunder, lightning, earthquakes, eruptions, disease, accidents, weather? Why do bad things (disease, accidents, natural disasters, death, etc.) happen to us? Why is the world as it is; how did it arise and what will happen to it in the future? What happens to us after we die? What is the best way to live? Do we have free will, or are we helpless bumps on the karmic log? What rules govern our existence? These are huge questions, and everyone would like to know the answers. But how could they possibly be answered? It seemed impossible for people to ever find out. And all over the world, people did the only thing they could: they guessed. They made up answers.
Since it was obvious that people didn't make the world and couldn't create or prevent celestial events and natural disasters, someone else must have - someone immensely more powerful. If we don't understand life and death and chance and fate, someone else far wiser must. So people invented gods and myths. What is thunder, you ask? Why it's made by Zeus or Jupiter or Thor or any of several hundred other versions of a god who makes thunder. Why does the moon change phases? Simple, it's one of the moon gods. What causes earthquakes? No problem - a god of the underground is restless. What happens after we die? We go to a better place where there are no diseases or accidents and everybody's happy. Or we come back and have another life. Or we become one with the gods. Where did the world come from? The gods made it. How should we behave? The way the gods tell us to. Every question is answered, nothing left out, no reason to wonder any longer. It was the perfect (and only available) solution.
And it worked, in every society in the world. People were happy to have all their questions answered. They loved their gods and creation myths, and they came to define that culture. We, and only we, are the chosen people, the ones created by and beloved by (our) god. We are the ones who obey his laws, and everyone else in the world does not. The others are wrong - perhaps just mis- or un-informed, but perhaps evil because they don't believe in the true god. The only downside was that every culture developed its own myths and gods and they were mutually exclusive. Each god declared that their way was right and all others wrong. This resulted in uncountable wars and genocides, which continue today. Still, a small price to pay for the satisfaction and security of knowing the answers to everything.
Then, probably around 1600 BC in Egypt, another method of finding answers was developed. It started in medicine. Doctors would try a treatment on an ailing person, then wait to see what effect it had. If nothing happened or the condition got worse, they would try something else. Writing was developed about this some time, so we have records of those early experiments. A few centuries later in Mesopotamia, people began carefully measuring the motions of the heavenly bodies and recording their observations. They discovered that it wasn't random motions, but repeating patterns. You didn't need gods and myths to predict eclipses, for instance.
The Greeks codified the new method of learning about the world, and called it science. Faith was not required. Someone proposed an explanation for some phenomenon, just as they had always done with religion, but then you tested it with experiments carefully designed to eliminate error. If you thought you had proved (or disproved) a theory, you told others about it and they repeated the experiment. If they could not, you did more experiments to see which of you had made the mistake. When an experiment could be repeated by anyone and they all got the same results, everyone knew that the right answer had been found. It didn't matter what you believed, what religion you were, what culture or continent or era you inhabited. If anyone didn't believe it, you could do the experiment with them and prove them wrong. Any high school class can prove the truth of evolution or the atomic theory or relativity. It was no longer a guess or an opinion or dogma - it was simply true.
The new method fairly quickly started running up against religious dogma, and the religious establishments, seeing how the irresistible power of logic and reason threatened their holy scriptures, fought long and bitterly to suppress science. For fifteen hundred years, the Catholic Church held back any advance in knowledge, while Asian, Semitic, and American civilizations quickly surpassed the Europeans in their understanding of the world around us. When the Enlightenment started to liberate European minds, however, that culture made stunning strides in pushing back the domain of superstition. Men could make and understand thunder and lightning, calculate the orbits of the heavenly bodies, peer into the distant past and future, and begin to understand our place in the universe.
The answers poured in: no, God didn't make the universe four thousand years ago - it was created 13.8 billion years ago; no, the sun doesn't go around the Earth - it's the other way round; no, supernatural magic doesn't exist - not one example of miracle, extrasensory perception, communicating with the dead, prescience, ghost, or soul has ever been detected in a verifiable setting; no, God didn't make all the animals at once - species are constantly going extinct and changing into other forms. No, it does not require a creator to create all the complexity and beauty we see all around us. Every time there was a religious belief or given truth that could be tested, hundreds and thousands of cases, science won every time. Not once did religion win by proving science wrong. Religion doesn't work that way. You believe it because you believe it and it can't be proven right or wrong. But if your religion makes some statement, and that fact can be tested, religion always loses. We know, with 100% certainty, that Genesis is wrong. Those events never occurred, and we can prove it.
In the face of all this new evidence, believers have become divided. Some cling tenaciously to their beliefs, insisting that their scriptures are the word of God and every word is literally true. As the evidence continues to mount, this position becomes harder and harder to hold. It means shoving your fingers in your ears and refusing to listen to any argument (or read any book), saying, "No, No!" with no argument to back it up. Millions of fundamentalists all over the world are doing this right now. But as knowledge of the world and the obvious effectiveness and correctness of scientific knowledge disseminate through our global culture and technology, surely this irrational backlash will eventually subside.
Other believers simply retract the borders of the realm of religion. Sure, science is right about cosmology and physics and geology and evolution. That was a bunch of creation myths those old guys believed in that somehow got into the Bible. The real story is that God is real, He loves us and listens to our prayers and we'll get to meet Him after we die. Science can never touch that faith.
In a way they are correct. No scientist will ever prove that God does not exist or that there is no afterlife. There is not one iota of evidence for these beliefs, but absence of evidence is not evidence of absence, as Astronomer Royal Martin Rees so concisely put it. But science has a remarkable record of being right about the world. We have spacecraft on other planets and GPS here only because both relativity and quantum mechanics can be written down as mathematical formulae and solved. If those principles - or any of the knowledge that supports them - were wrong, these things would not be possible.
If you made a table of reasons to believe or not believe in God, 100% of all experiments, physical data, and known facts would be against it. No experiment has ever confirmed a religious idea. There is no evidence that prayers work or believers have better lives than non-believers; that miracles occur, now or in the past; or that there is a heaven, hell, or any other kind of afterlife. On the other side of the ledger, what reasons are there for ignoring 100% of the evidence and believing in a God that can never be proven? There is only one, and it is so glaringly obvious it constantly astounds me that many believers seem to have never thought of it. We want to believe. It feels good to believe that there's a powerful, beneficent being who understands all the strange and terrible things that happen in the world; that loves and values us; that our lives have a larger meaning than just procreating and dying; that we will live again after our deaths and be again among the loved ones we lost. God has a plan, and he has rules to live by. We don't have to wonder what's right and wrong, whether what we're doing could have terrible and even fatal results - it's all in the book. We're not confused and scared and unsure aging adults - we're children, guided and loved and protected by a caring, wise, and all-powerful father. If you were trying to make up a happy comforting myth, you would make up exactly this one. And we did.
Of course, there is another powerful reason to believe in a religion. It's what is taught to us as children. As we start to learn about the world as infants, we turn to our parents to provide the knowledge. They teach us so much - how to behave with others, how to avoid getting injured, how to dress and talk and eat. Most of what we know we learned from them. And when they teach us their religion, of course we accept that too as truth. Why should we doubt them, when they have been so reliable in every other way? So all over the world, children grow up in their parents' religion, and they pass it on to their children. If you had been born in Iraq, do you really think you would not be Muslim? No one reasons their way to religion. The number of people who come to religion as adults or who change religions (other than for a marriage or to avoid discrimination) is vanishingly small. And where scientific knowledge is readily available and there is freedom of thought, even people raised in a religious upbringing frequently abandon it.
To my mind that's the distinction between atheists and believers. Some of us want to know what the world is really like and turn to impartial science for our answers. Knowledge allows us to take an active part in shaping the world - to try to avert climate change for instance, or plagues or mass extinctions or depletion of resources or avoiding a comet impact. Believers would rather not know the facts because they'd rather feel safe. They truly believe that what you don't know can't hurt you - one of the silliest and most demonstrably, dangerously incorrect aphorisms ever created.
