God has always been the ultimate deus ex machina for people unwilling to really analyze a strange event. In ancient times, it was lightning, thunder, volcanoes, etc... now it's a cosmological event. With a sense of history, we realize that all these things eventually saw a naturalistic explanation; the Big Bang will likely be no different. God will then run and hide to the next dark corner of human knowledge.
I think we're all looking for answers to the same questions, some people are just satisfied with "welp, God musta done it." Others remain unsatisfied with that hypothesis.
Neil DeGrasse Tyson said something similar:
(YouTube video)
"God is an ever receding pocket of scientific ignorance that's getting smaller and smaller as time moves on."
"If you were so content in that answer...the day you stop looking because you're content god did it, I don't need you in the lab! You're useless on the frontier of understanding the nature of the world."
I pose a question to theists. I think most atheists, myself included, would perfectly accept a god if it were found out to be true that one existed. I have no problem with that. I would indeed accept that one existed if sufficient evidence were presented. Even be grateful if it was the reason for my existence (worship is a whole different question all together, though).
Now, I ask, if sufficient evidence were presented (hypothetically), would you accept the non-existence of the god. If all your questions were answered of how life began, how the universe began, what happens after you die, etc. etc....and non of that ended up being caused by a god, would you accept it?
