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.
Lemaitre did it scientifically without the supernatural, and he was a priest.
That's the equivalent of throwing up your hands and saying, "It's too complicated for me! It must be magic!"
Call it God or call it Joe, whatever gets you going in the morning, but how we got from an infinite cause across a rather tall conceptual boundary to an anthropomorphized bearded guy with an hour glass and an obsessive interest in human moral behavior is beyond me. The moralizing God is more like my mom and dad and their cultural folkway memes than any all seeing, knowing, powerful trans-everything.
