@Pnakasone: ....Dude, it's not "human civilization", it's "civilizations". Difference? The first would refer to mankind, in which case it would be pretty obviously wrong. The second refers to the many civilizations that have risen and fallen, which is, in case you failed history forever, exactly what has happened with human civilizations in real life. Egypt, Babilon, Rome, and many others. Alas, it doesn't mean mankind has been destroyed.

@Cyrania: The first idea sounds sort of like bullshit, especially if the Faunus have been existing for thousands of years, or even ages, in which case I doubt they had enough technology to create half-human hybrids so far back, even with Dust.

For the 2nd idea:

Existing since the same time as humans but never met until much later? Possible, it's basically what happened with America.

As for the other possibilities you mentioned, regarding the Grimm:

-"Product of alien experiments">

-"Souls of murderers and criminals". If that was the case, they would actually be successful at killing people, especially helpless people with no way of fighting back like back in Breach.

-"Physical Nightmares". Well, they are the sweetest, most harmless nightmares I've ever seen. Seriously, they are so weak and pathetic, only a kid afraid of their own shadow would consider them a nightmare.
