Honestly, until a couple of weeks ago I had no idea of the existence of this movie or its plot, I found it as Ridley Scott's new "film project", and when I read a little bit more about it, I just froze!
"A group of archeologists discover an ancient chamber full of hieroglyphs which tell of an advance alien race and the creation of us humans, the chamber also contains two items: a DNA code, and the space coordinates of the creator's home world.
Then a team is assembled and sent into space to investigate."
According to some websites the DNA code found in the chamber might be a gift from the "creators" that allows the breeding of some sort of bio-droid. I've also read that two of the expedition team members are ment to be synthetic (possibly bio-droids).
The "creators" race is supposed to be the same of the "Space Jockey" we met on the first Alien movie (the giant guy seated on what seems a huge cannon with his chest open). Finally and more important!, it seems this guys are also responsible for the creation of "the xenomorphs we love" as a cleaning device...
