Stephen Baxter Quote

Her story was a creation myth, a legend already more than twenty thousand years old. Such tales—which said that Jahna's people were the pinnacle of creation, that theirs was the only right way, and that all others were less than human—taught the people to care passionately about themselves, their kin, and a few treasured ideals.
But to the exclusion of all other humans, let alone such non-people as the Old Man's kind.
