I will answer your question with a question.
Where did matter come from?
The answer to your question must wait until you can ask God directly. He didn't cover that topic in His message to us.

Not being a scientist I can't say. I majored in Art History for the vast and lucrative post-graduate career prospects.
But I THINK it must come from the same place socks GO when you lose em in the dryer...
That's just a theory mind you.
I don't see any problems believing matter always existed and the space it fills expands and contracts in a never ending cycle.
Of course it would be just as believable that God always existed except I've never seen any proof that God exists but I observe matter almost daily. So I tend to give more credence to the matter thingy.
No offense intended.
I just ANSWERED this!
