“We may never know how advanced man became between mass extinction events.”
My thought for a long time exactly. Also, what was the trigger for the change from 40 ky ice events to 100 ky ice events starting about a million years ago. Could there be a cometary long orbit cycle responsible? And have scientists or interested amateurs examined maps to detect other subtle comet type craters?
Some seem to indicate a comet that would appear in close proximity to the Earth for six years then, eventually breaking up and impacting the planet. This disaster would preclude the coming of the AntiChrist’s reign.
Are you aware of any such comet that makes regular visits to our part of the universe?(not trying to get all Biblical on ya)
