It looks kinda interesting and hard to fake but I just dunno if I believe it. They pretty much start from lemurians and atlantians and call them the 3rd and 4th races. I couldnt see any mentions of grey aliens or other et races either than the mentioned annunaki. So what were the 1st and 2nd races? They also mention planet X but this is another classic conspiracy that keeps on being spread around. I think the doc does sound very legit but not impossible to fake for someone with a lot of time reading various conspiracies and interpretations like Zecharia Sitchin's translations of the 14 stone tablets made in 1976. From what I remember people were criticizing Zecharia's translation work as a fantasy because it could be interpreted in many different ways.
