That's non-controversial, regular knowledge right? That the proto iron age happened all over in 1 or 2 centuries in which meteors dropped iron from the sky. It was in regular history books when i was a kid.
They always brush right over why it was raining iron. Isn't that crazy wth is that about?
The most recent book i read relevant to the time period was "4000 years ago" by something Bibby. Definitely it made mention of it whicj made me recall regularly reading that and raised the question.
4, 6000 whatever lol the chalcolithic
Mmkay. I personally have never heard anything like what you are talking about. Other than your post, I STILL have never heard anything like what you are talking about. I'm not going to say you're wrong, though I have seen no actual evidence to support such a claim, but I will say that it is far, far, far, far, far, far from "non-controversial knowledge."

Ah. I misunderstood what you were talking about. Yes, its possible our first iron was from asteroids because it didn't need to be smelted to be used. In asteroids, especially after surviving the burn off from entry into the atmosphere, it is already in a relatively pure form.
I don't know if it's true that we only used it in that form prior to relatively recently. I've been seeing a lot of stuff lately about us having knowledge of smelting iron going far back, but it looks like it was lost knowledge. During the time period in question (3-10k years ago), it is entirely possible that it was gotten from asteroids until we "relearned" how to smelt iron a couple thousand years ago.
Well 1 tension in your timeline is thinking "man" had this technology andmaybe not "some men" who probably made up stories about it and only taught sycophants and hucksters the racket and the cover story
