Two competing theories and neither satisfy me.. The truth is that nobody knows.
Nobody? No human.
I’ll pray for your mind and heart to be opened to the truth. Read Norman Geisler and Frank Turek’s book “I Don’t Have Enough Faith to be an Athiest” and maybe the light will come on for you. Plenty of science, history and logic to prove that creation is true.
Think larger. What WAS before the Universe began? Explain an endless eternity with no beginning and no end without God. Explain a Universe that has no dimensions and is endless in every direction. If Time and the Universe have a beginning, or an end, what was Before and what is After? The only explanation is a God. Science is finite. God is infinite.
I know, because God tells me in his word how we all started. I take him at his word.
Oh yes we do. The One Who is eternal certainly knows. I'm sticking with His account.
