You certainly don't, and you certainly aren't, but I think you do believe in God --the god of Galileo, Newton, and Darwin, whose name is Science.
No - this is entirely incorrect. Galileo, Newton, Darwin, were mere men. Humans. Not Gods, just thinkers. Brilliant people. Unless, of course, you have a very different definition of a God than I do.
There's also a lot of talk about "Science" in this thread that misunderstands what it is. There is no organization or membership to "science". Science is simply a process, a standard way of learning. There are millions of scientists doing work on the planet, and their allegiance is only to the process, not to any belief system. If you're suggesting that believing in a standard is akin to believing in a God, then a belief in God is rather flimsy.
Now, some scientists have not strictly followed the scientific process. Some have lied, some have misled. Usually you can follow the money and find their research is being funded by large corporations, or they want fame and the funding that comes with it. That's a crime like any other, but it doesn't bring "Science" into question. By definition, they've either not followed the scientific process, or they're flat out hiding results contrary to whatever it is they're announcing.
How did we get here? Well, personally I think the entire universe has a set of rules and likelihoods. We don't know them all yet, but they're there. We occurred because, mathematically, we were inevitable. Which is why I believe there just has to be life on other planets. We're the result of chemical interactions. These interactions will have occurred in many places, but weren't able to flourish so quickly went away. Really, for me, it's about extending the idea of "mother nature" out into the universe as a whole.
