Pretty Much Proof Ark Was Real. Not Alien Theory.
Alright so I am very sure, after watching this 3 times so far, even though I watch it and believe it for the messages, the inspiration, the wisdom, the shear brilliance of it.. i always wonder what really is the ending, and this has to be it.
Earth built the ark and were building on it, and they kept Lee on the spacestation because they knew they were at war, couldn't take him down and that earth was going to be destroyed. They knew this and, in congjunction with the journal, the General wanted the Captain to be the sousurvior, to write about what happened, what he found.. he was the last left and he did.
Lee on the spacesation is doing the same exact thing, houston sent him up there, they knew everyone was going to be killed, so they wanted someone to retell the story, to be a soul survivor.
WHAT PROVES THIS: The second talk he has on the spacestation around 10 mins or less in, houston says something "Can you send us your coordinates, send it in 8 data packs.. or something.. " and he says "thats a hell of a projection" , all like thats weird for them to ask, but he sends them and asks why and they say "we want to see if we can remotely keep that station in orbit.'
BOOM.
They knew earth was done, they wanted a soul survivor, they found out they could keep him in space and he would always be in orbit until they could arrive, if they found him. They did it remotely and then everyone died. So at the end, the Ark is a real thing, it recorded just historys most prestigous human events, human wisdom, etc. and kept then sent it up to Lee with a prerecorded message. Then he finds aconnection hes been looking for, everything in the bulding is a connection, the book, the computer, etc.
What the space stuff and the room he walks into is, im not sure
