On the subject of which day most changed history, and in the spirit of Freeman Dyson's suggestion (Chixculub); may I put forward the day when an object the size of Mars crashed into the proto-Earth and started the creation of the Moon, in the process making it possible for life to evolve?

Without the Dinosaur Killer there would be no us. Without Thera (the most common name for the object above) there would be no life on Earth.

There is, of course, a serious point here. There have been many people whose birth (or death) changed history; but none of them compare in potential effect to another Chixculub asteroid, Yellowstone going boom, Cumbre Vieja sliding into the sea or the Western Hemisphere being hit with a major CME. Just to give some examples.

We need to get some of our eggs out of this basket. And one more suggestion for "the day that most changed history" in the "human action" section; July 20, 1969. This day will be remembered (perhaps under another name!) when all the currently existing works of Man on Earth are dust.
