Either the universe has always existed, or it came to be out of nothing. Either way is mind blowing.
God did it. And He has always existed.
“Mind blowing”.
Always existed implies at least on the dimension of time infinity and as finite humans we cannot really comprehend that. Therefore I think there is a bias for us to favour an actual beginning and eventual end to the universe. God can also be considered infinite so again our ability to comprehend that aspect is beyond us.
