What hogwash.
It turns out that the notion of a big bang being a true beginning to the universe, with nothing prior to it, sounds too much like a scenario in which an all-powerful God created the universe.
So, to solve that problem, they come up with a theory that includes a “soft open” prior to the Big Bang.
Man says to God, “We don’t need you, we can make Man from dirt, just like you!”
God says, “Ok, show me.”
The Man picks up some dirt, when God interrupts him, “No, go make your own dirt, first.”
