"Spot me 900 plus years, give or take, say 300, probably right on the money, for the first event, step forward 500 years or so for the rest of the events,at regular intervales through say 1200 BC?" Okay. I have catastropic (worldwide) tree ring events at 2354BC (start bronze age), 1628BC (The Exodus), and 1159BC (David Plague),and 207BC (minor event). Will any of these work?
You're missing the East African event of around 3500BC +/-. Remember the Arabian coast on the Persian Gulf was an extention of the Summerian culture until about 2000 +/-BC.
