I have run things over in my head again and again and i must say im still unsatisfied with any theory. The 'eccentric' general made me think that in ages past humanity pushed themselves over yhe edge with countless wars and un ending fighting amongst themselves. In a last ditch effort of the remaining few trying to save and unite humanity, it was thought that uniting against a common enemy would be the only way since the only way to survive would be to work together. The plan was used amd to their horror the humans didnt stop fighting....they kept it up and the 'titans' that were origibally created as a catalyst for unity ended up out of control. Once defeat was accepted the walls went up out of sheer despiration and the titans roamed the earth. They dont require food save sunlight and their odd steaming and materialization mean something very wierd is used to create them. Now those humans that created the titans legacy lives on in the serum and the central government inside the inner wall knows far more than they let on being remenants of the original powers the titans were created to overthrow. Something tells me the titans attacking yhe wall and their hate for humanity comes from a far more justified place than we might think now. The government in the inner ring might be the real evil here.

Also, another less likely theory is that they arent on earth at all. The planet could actually be the homeworld of the titans which would explain their non need of human flesh to live but their avid desire for it considering we probably commited atrocities to their species in attempts to colonize their world.
