We have historical text records of all Creation, given to Man by God, which explain the origin of everything including the spiritual rebelliousness exhibited by those who have no Faith.
Now, the Faithless are demanding proof of God's existence, or merely stating (as if they somehow knew) that there is no God. Hogwash. It is entirely the responsibility of those puporting a new, improved explanation to prove their position, not the other way 'round.
Let scientists prove that God did not create the universe, and does not exist. Good luck.
