Air at sea level is compressed, relative to air at 10,000 feet.

So who does that? Or is it just in the nature of gravity, and air to produce it without the personal intervention of a personal G-d, a personal G-d who really really wants me to believe in him, but who somehow can’t be bothered to make me a phone call.

I do not grok a "who". I do not grok a "doing".

Gravity and pressure are not relevant to evolution and Darwin, either, except insofar as they affect creatures striving for new ecological niches.
