Charles Magee, Jr.'s Fermi paradox meets the timescale, where this field geologist sees the question through the lens of deep time. "As a geochronologist, I don't wonder where and why, I wonder when," writes Magee, who goes on to generate fifty random alien arrival times within the approximately 4.5 billion year window since the Solar System emerged from its accretion disk. He lists them in order, the most recent of them being 125 million years ago in the era of the dinosaurs. That appearance in the Cretaceous is preceded by an alien visit at 270 million years ago at a time of Gondwanan glaciers, and a 352 million year old visit in the Carboniferous era of swamps and giant insects... Keep going back in time and you realize what a tiny veneer our own species' existence represents over the deep time that encrusts planet Earth.

This is one of those rare topics which can fit in all four of the ping lists I manage. Thanks go to LibWhacker for posting it.

I don’t know what’s true.

I do know that God said . . .

yea though you build your nests amongst the stars, yet will I bring you down.
