I would answer, “I have seen no evidence of an afterlife.” I would of course have many questions for god. Why did you stay hidden? Why did you reveal yourself only to primitive people? And I expect that god would be proud of me for not believing claims about it. If the god was insecure, then it might be upset that I did not believe in it.
The big bang is simply a scientific theory describing the birth of this universe. The question of who or what caused it is one of those great mysteries. People made up stories to try to explain these mysteries. I don’t put limits upon the universe by assuming such things as Big Bangs don’t happen more often, or that there is only one universe. These are big questions that I don’t pretend to have the answers to.
Code:
What about all the miracles and supernatural events attested to by all the OTHER religions of the world throughout time? No supposed "miracle" has ever been substantiated.
What people? Who? What miracle?
The opposite is true. There is absolutely no evidence of god. Name one miracle, and I will demonstrate that it is unproven.
