I feel that the website godandscience.org (mainly the cosmology parts) offers a lot of good suggestions from commonly accepted science for the existence of God, and a personal one at that. One of my favorite examples is the long list of examples of qualities of the universe that highly give the impression of "fine tuning", enough to where it seems absurd to think that a non-designed universe could even result in a universe that could even result in matter, let alone living things. Some of these things that seem to be fine tuned are the rate of exansion, the ratio of matter to anti-matter, and certain aspects of the laws of physics; where with each of these the universe would be vastly different and unsuitable for matter if they were changed by even the slightest amount yet could have easily "happened" differently. I for one feel that these are good evidence for God, though definitely not direct proof as many will say.
I don't think science "proves" the existence of God, but I think it provides a rational grounding for belief in God. Expecting science to produce undeniable proof for God, seems unrealistic whether God exists or not. What would hard proof of God look like, to where even the most stubborn atheists can't deny it?
