If reading Grant Morrison has taught me anything, it’s that aliens don’t actually come from outer space, but rather from other dimensions. They live outside of the fourth dimension, you see. So I’m not sure if there would really be skeletal evidence. Comics have taught me so much. I should be a scientist. Regardless, this skull gives me the willies. How long until we discover that this is a hoax, do you think? The comments on io9 point to hydrocephaly. I’d buy that.
