Not to throw a monkeywrench into the works but:
How do we know that's not how God did it?
How do we know that all the chunks of matter in the universe aren't like a huge 3D bunch of paddleballs, that come back and collide into one big lump, and then heat up and explode again...every few zillion years or so?
Just like a looped film of a single July 4th fireworks aerial display, first running foreward, and then backwards...then forwards again.
Sorry Cboldt, forgot to ping you.
I, for one, trust God to have done “it”, no matter how “it” was done.
