As one of my old professors once said “The Earth is an Icy Planet with vast areas suffering from long term cold. However it is punctuated by warming lulls, thats when civilization happens!”.
Absolutely... It is a cycle. But something that is being misconceived is civilization and technology have never been linear and universal world wide. There are still remote cultures even now surviving with stone age technology.
Meaning while there may have been rudimentary technology in one geographical area, there very well could have been very advanced technology in another. One cannot be used to invalidate another.
It is a mistake to assume that technology was universal world wide as linear in the timeline.
I tend to believe Clovis and pre-clovis we’re mostly erased about 13000 years ago with a Younger Dryas impact event. Sucked to be northerner. But some middle folk pushed south and both they and the southerner’s remembered, in pieces, imho.
The ultimate game changer.
