[40K] So, dumb question, is the Emperor really human? Also; It is heresy to ask about that kind of thing?

Hey everyone! I'm a Farmer from Planet M-52//3, and I have a conundrum. In our town we have a church devoted to the Emperor, and he's depicted as a ten-foot-tall musclebound demi-god with incredible powers!  Even more amazing, the local preacher says that he's a human! But I've met like, 30 humans. And the most amazing thing that I've seen any of them do was when Everett hocked a loogie 10 feet after drinking a glass of milk! 

As a human, I kinda feel defined by my smallness compared to the grand scale of the galaxy. Whereas the Emperor is friggin huge in the Metaphysical sense, AND the actual-physical sense! 

So is he really human? I would ask the preacher, but he has a chainsaw and eviscerated the Frankinson boy for asking whether Space Marines have functional peckers or not.

The Emperor was born to human parents, and is the reincarnation of a bunch of shamans of Ancient Terra. Whether this qualifies him as a human is up to you. He is in fact 10 feet tall and biologically immortal, as well as being a reality warping psyker. maybe he made himself ten feet tall using his reality warping pysker powers. It is not our place to ask questions about the Emperor, it is our place to die for him.
