According to this timeline http://www.ironhands.com/40time.htm
the Emperor was born in 9000 BC. So between then, and year 28,000 AD, what the hell was the Emperor doing? There is the debate as to whether the Emperor is a god or not, it would seem to me that someone who is 37,000 years old would most definitely be a god (well, 49,000 years old I suppose, or 39,000 if you don't count the years after Horus mortally wounds the Emperor) - No matter what way you cut it, he's pretty damn old. SOMETHING had to have been going on with the Emperor between the time he was born and the time he created the Primarchs. It may be somewhere in the fluff that I just haven't read, but I'd like to know what he was doing around all the historical events we currently read about in history books, or what he was doing in year 2011 (bitching about the oil spill?). It may just be one of those things that was written to be cool, and never spoken of again. And it may be that the Warhammer 40k universe should remain seperate of that from our own realistic universe. But there are so many references to real events, myths, and so on, as well as the reference of Terra being a "new" earth.
Kind of a mind fuck in a way
Anyways, what would your thoughts be on this, or maybe some existing fluff?
Oh, and one more thing, I saw written somewhere that one of the mysteries surrounding the Emperor is that he is in fact Tzeentch...sounds pretty ridiculous to me. Is that actually a supported mystery, or is it utter and complete bullshit (as I take it to be)?
