The only objection I have to your scenario is that you have God in a timeline with "After" creation and "pick a piece of it" and "install life" and "tweaking the basic design"...........no.......I don't think so.
God, timeless/alpha-omega, acts in what we could only describe as '
Simultaneity'... God says "Be" and (from Gods perspective) it all is...there iis nothing to unfold or "tweak"...
Evolution is law/principle set to auto...like gravity...God need not adjust the ascent or the descent.[/quote
So...Wombat...
Linear existence...you and I....one moment to another...
God is Spirit.
If He moves from one moment to another...it is, that He moves with you.
Physical rules are not likely to apply to Him.
They apply to us.
