I like to think it was some sort of a meet-cute set up in a Rom Com. Only between two atoms that then exploded.

Starlight, dead astronauts, and unicorns.

The first 'good' came when the first living thing realized it needed some other living thing to survive.

Truth is relative. Find the largest lack of lies and go with it.

Probably to entertain someone very powerful.

To keep things interesting for God.

A really long dream.
