You solved the X-Files! Great analysis!
I do think you are missing a key part that shows that this is not a downer ending for humanity on the making: God.
Let me explain my personal theory of the rest. The aliens met God and he instructed them to give us those holy books and mix their DNA with ours before they left…

Carter has lied a lot of protect plot points so I don't take those declarations in account too much. He does write things last minute to avoid leaking but that is kind of standard specially since the Internet was already starting with the leaks and spoilers ruining the experience and Carter is very secretive.

In fact I think she changing her will to allow herself to die might had been because she found out she will be more useful in the other side,…
