1.) God, being all perfect and all powerful, cannot create anything
imperfect.
2.) But if God's creation were perfect, he would have created another God -
a contradiction (a created God)!
3.) God's "out of the box" solution was to invent "time" and "evolution":
His creation would thus forever evolve closer and closer to perfection,
always becoming - but never being - God.
This is a devil's advocate argument for the necessity of evolution in
Theism, from an atheist - perhaps an agnostic - I'm uncertain about that.
