It's quite sad really. I'm not a scientist, but I've learned enough of our universe to know, that there are plenty of places for a god to hide. We have all this dark matter and energy we're not really sure about, and the whole quantum mechanics stuff seems close to magical and has a lot to do with probabilities. We don't even know how gravity works. Oh and then there are the dimensions that may exist even though we don't seem to be able to observe them.
Now an entity that has control of these things would be pretty close to god in my book, so doing science and learning new stuff doesn't mean you have to accept that there's no god. Besides - no matter how much we learn, every answer brings more mysteries to solve, so it's not like you're ever going to know everything and prove that god doesn't exist.
