Swarm C: Cl - 1 Strike
The evidence of a great cataclysm between 2200 BC and 2190 BC is so compelling that on this basis we can't dismiss it. On the other hand, Courty is right in her theory of a major occurrence which I would date between 2350 BC and 2340 BC. I suggest that there really were two disparate events, a local one in Near East 2200-2190 BC and 150 years later, 2200-2190 BC, (likely means 2350 - 2340 BC) a global one.
I just don't know anymore. Looks like there may have been two impact events (geez) one at about 2200BC and one at about 2350BC. The one at 2350BC (2354BC?) was recorded in the tree rings worldwide. Lots of fireworks in that time.
And ~2200 should have been Noah's Flood. Maybe a large comet melted into a stream of water and small asteroids and the earth sucked up the debris a couple of passes.
