Because we scientifically know that everything that has a beginning, has a cause.



We've already discussed this. This statement is scientificially nonsense. So I'm surprised to see you post it again. Bell's theorem was long ago proved. No cause is required for quantum events. As to the universe, it is in fact unlikely that it had an external cause. Almost all scientific hypotheses about the beginning of the universe either point towards an internal cause, like a phase transition, or to no cause at all.

If you still insist on it, can you give me a single serious scientific theory that assumes an "outside" cause for the beginning of the universe?
