Do you belive that in the (distant) past there existed civilisations that we know nothing about? Do you think this is possible?
I can imagine a civ existing before the last ice age, and reaching something like the Sumerian level.
Or perhaps a civ in an "exotic" location existing as a contemporary of ancient Egypt.
