How do you see human history?

Apparently these are the big stages of human history -- the transformational events:

• The use of fire — from at least 250,000 years ago.
• Language — from at least 40,000 years ago.
• Agriculture — from at least 10,500 years ago.
• Civilization (states) — from about 5,500 years ago.
• European conquests — from the 15th century A.D.
• The technological-scientific (r)evolution and the dominance of fossil fuels as primary energy sources from about the second half of the 18th century A.D.

Hmm. Makes perfect sense. But I'd never have thought it was so obvious until I saw it laid out like this. It's like those things you know without knowing it, and when you know them, you think you must have known them all along, but of course you didn't, even though you feel you did. (If you can follow what I said, because I don't quite.)
