I’m going to try a serious answer now.
The traditional view of the Big Bang is that when it occurs the universe comes into being. Time appears as a dimension, or a quantity, constrained by the universe. It doesn’t make sense to talk about time outside the universe or before the universe just like it doesn’t make sense to conceive of matter oustide of the universe either. Time is a consequence of the ‘rules’ of the universe.
What that means for Christians, if I may be so presumptuous, is that before the universe existed, there was no time. Anything existing before (tricky word to use) is timeless. One could argue whether something could exist in such a conceptual nothingness. I can’t answer that.
I was forgetting Stephen Hawking, our present time equivalent of Einstein. He came up with ‘virtual time,’ a time line that is infinite and unbounded by the Big Bang. Actually, Hawking wants to do away with the whole concept of Big Bang, but when I try to follow his explanation my brain overheats. As for virtual time, I don’t know anyone who really understands what that means, not even I. Sorry to be incomplete.
Only humans do inhuman things.
