Hmmm... As you can probably tell, I'm not big on proofs or expressing things
formally, so maybe it will be safer if I continue to talk plainly.

When devising a Theory of Everything, anything goes, except you must be able
to demonstrate the universe in action. At least the beginning part.

You must specify, exactly, what the initial conditions are, and what the
procedure is for transforming the initial conditions into the future states.

Following the instructions you specify, we should be able (in principle) to
see everything we see now. The ground, the sky, the sea, people, plants,
and animals.
