Reply to comment by OceanIsVerySalty in Obsidian handaxe-making workshop from 1.2 million years ago discovered in Ethiopia by rmaccr

I suggest a more thorough research - there are a lot of evidence about that but as it hasn't been in line with the "main stream history line" one needs to dig it out.

Ever wondered why ChatGPT worries so many main stream media and some IT companies? Because it will have an unrestricted access to everything that is hidden in a plain sight.

Try to do some math yourself - someone was manufacturing obsidian axes 1.2 billion years ago, your ancestors were manufacturing similar axes from stone 50k years ago. So nothing ever happened to a previous civilizations in between? 1 billion years passed and all we did in that time was to "manufacture" primitive axes. And suddenly a few thousands years ago we went to iron age. And since then how many years passed? 1 billion? Or just a few thousands?

So once again - it is great that this obsidian axe made into media.

Using various paleoclimate proxies such as ice cores and sediment samples, paleoclimatologists have been able to pin point events such as the Permian - Triassic extinction event 251.5 Mya, the K-Pg boundary 66 Mya when an asteroid / supervolcano killed the non-avian dinosaurs and ended the Cretacious, Paleocene–Eocene thermal maximum 55 Mya, and many more. They get more and more accurate the closer to modern time they get.

A mass extinction caused by a nuclear event would not go unnoticed- especially as recently as the pleistocene. There would be evidence of decaying or decayed radioactive isotopes.

If you are interested in such things as past human-oid civilizations, I suggest you put your mental energy into learning about our closest relatives such as Neanderthals, Denisovians, and Homoflorensis. Or more distant relatives like the Ardipithecus family from ~ 7mya. Truly fascinating stuff.

Otherwise, if you continue on this conspiracy theory path of "past nuclear civilizations" based only on the fallacy that it's impossible to prove something DIDN'T happen; you will end up another ancient aliens nut case or Lock Ness Monster truther and deprive yourself of a whole world of fascinating REAL knowledge about the world and it's past. Even fueling harmful controversy for real researchers trying to conduct real research about past civilizations. Please don't be one of those people...

Here's a PBS Eons video to get you started in the right direction if you enjoy learning about ancient humans
