OK this may be dumb but I recently rewatched Nasica and the valley of the wind. The titains remind me of the super shoulder at the end. Don't really think there related but more comparisons could be made.

My real theory is that the show is not on earth we teraformed a planet seeded earth plants and animals but the titans are a native strain of life that changes humans. But it took so long for it to develop that like in other SciFi shows we lost the tech that brought us here.
