ok genius, explain it to me.
I’m just saying.
You said you couldn’t imagine it.
I’m just saying if you had a physics degree, you could imagine it.
Even less than that, just read some good popularizations of Big Bang theory.
I’m not saying that makes it “true”. I’m just saying such things would go a long way to addressing your admitted inability to imagine it.
If you are a person of faith, you will find much in these books to delight you. I'm sure you know that providing a scientific explanation for how the universe got started doesn't preclude a belief in God, as many theoretical physicists do. Some people just like more of an explanation than "Let there by light."
