Tbh, I think the creation of the universe goes beyond anything the human brain could even think of, there is alot humankind will never explain, but just because we cant explain it doesn't really mean some magic man in the sky made it.

The same applies to god though... who created god? If god has always been here then whats to say the universe hasnt always been here? And to talk about before the big bang, there is some scientific proof, I read somewhere that the universe was once the size of a grain of salt and it exploded outwards... and is still expanding.
But that was ages ago so im not sure if its right. But there are ideas to what has happened, but this whole universe is complicated. much more than we can understand.
