I already made a thread because I didn't understand.
I just finished the game and I still don't really understand.
I had two endings to choose from, I chose the ending where Eve merges with Adam.

1) So if humans are Naytibas, why are they made in some kind of egg and look like monsters ? Where are the normal humans ?

2) Do you agree that absolutely all the inhabitants of Xion are robots ? As Angels ?

3) How can Adam (a human who has undergone genetic mutations ?) merge with a robot ? If a human puts his finger in a USB port, it won't do anything at all.

4) The best ending if we are on the human side is fusion with Adam or the other one ?

Thanks
