I don't think scientific gaps prove God, they are openings for further scientific progress...but those gaps make for great places to insert God, gods or god-like aliens into well crafted modern literature.
One good example is the wormhole aliens in Star Trek: Deep Space 9. They exist outside of time. As such they seem to have some capabilities of prophecy for that reason. We understand that the nature of space is also the shape of time and so in Star Trek we see some sci-fi interpretations of the future possibilities through technology of how we might be able to transcend our current limitations within space-time. Now we might also gently set aside some of the contradictions in our current scientific knowledge that are also displayed in that show such as noise in space and the invention of trilithium crystals and such. We do this not because we are bad scientists but because we are in a frame of mind to be entertained and even inspired as to what the future might hold for us, but also the possibilities of human ingenuity to solve problems that more powerful beings or forces might present to us.
My god is first and foremost a literary creation meant to tap into what I would claim are objective aspects of human psychology. I do not worry or concern myself with proving the objective physical reality of God.
This is probably such a watered down version of God that I don't think that you really want to argue with me.
My strongly atheist step-daughter and I agree on many things except the value of faith. But even there we are both in agreement on the belief that Terry Pratchett's book/movie
Hogfather is awesome because of this dialog:
