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?
I suggest watching The Thunderbolts Project on youtube for a new take on our Planets history. It suggest major events like The Grand Canyon were created in hours not millions of years from huge Lightening strikes, caused by massive objects and micro novas that lead to planetary size lightening, if you look at the Grand Canyon from Google earth, it looks like a lightening strike. They bring receipts too.
