There’s some quite interesting sci-fi concerning the history of man, from Larry Niven as well as the Halo series of video games and books.
When I read Asimov, Heinlein, Pournelle, Ellison, Farmer and others at my mother's knee, I was taught to NEVER say "sci-fi." It is "Science Fiction" thankyouverymuch!
You invite the wrath of Campbell! Look and be terrified (no wait, that is Lovecraft)
PS: I spelled Pournelle's name from memory! No one was more surprised than me I got it right!
I've read Niven and Pournelle and I still get my butt kicked at Halo.
And there ain't no mote in my eye. Stinkin' Moties.
