In fact there was no life at all.
Scientists now believe life began in a far more hellish environment than some kind of Frankenstein laboratory with lightning somehow creating life in primeval soup.
Most likely life was created by thermal vents deep in the lightless, airless recesses of the ocean. Cracks in the ocean floor opened to a hellish heat created by nuclear fusion that will continue until a dying sun engulfs the earth.
Today such vents are still alive with alien life that cannot survive the sun and oxygen-rich environment of the surface.
Anaerobic archaebacteria created that oxygen-rich environment from the poisonous methane that filled the atmosphere and then died from their handiwork.
Nitwits who call themselves environmentalists and pay no attention to science would return much of the stored methane to the surface and the atmosphere and call it clean energy.
They revere the distant sun, which will eventually destroy the earth, with its relative dribble of sometime energy and mostly ignore, or even denounce, the massive energy available from Mother Earth herself and her prodigious production of vegetation.
These fine folk even prefer to fill the land and waters and air with their own waste rather than recycling it for energy.
What kind of environmentalism would that be?
