No. A Big Bang would be a natural phenomena within the boundaries of the physical universe. Not magic.
How exactly it happened is debatable and there very well could be other scenarios. But any attempt at a scientific explanation is better than a supernatural magic answer.

You speak of Intelligent Design.
Question: Who created the Intelligent Designer? Then who created the creator of that designer? And on and on backwards as far as infinity. No one has ever been able to logically answer that question.

1. The physical universe created by God or the one that magically sprang from nothing?
2. For atheists it is.

Again, faith. God, or came from nothing.
