All the white people and chinese people building massive amounts of DUMBs to protect themselves in after all the doom will eventually evolve into the reptillians and greys, respectively, and they have returned to harvest people they knew died in the original doom, before they actually die.


This way, there isn't any affect on the timeline from taking their ancestors from the past. What they plan to do with us is anyone's guess, but it may have something to do with them all wanting to evolve to look like Charleize Theron instead. Pretty fucking fed up with scales and giant bald heads, they want to be statuesque and have big tits instead.

I enjoy thinking about this concept, it is interesting, but I don't believe it to be the case. But, it would explain why they keep living inside of the earth instead of up on the surface with us. If they are from the future, maybe even a future world where the planet no longer exists, so they came BACK IN TIME just like on that failed tv show TERRA NOVA. They continue trying to not intervene in the daily lives of average people but convince out leaders to take the earth down a diferent path, since they know we totally fuck it all up on our current one.
