Its an Alien 'Remake'

The more and more I see of Prometheus in the trailers ,the more i believe it is indeed a remake of Alien. Ridley once said the franchise was like a sponge that had been squeezed dry. I believe Prometheus is to revive the franchise. Also certain similarities between Alien and Prometheus are starting to arise... The derelict signal is now cave paintings/map They land on an unknown planet and things get out of hand A corrupted Android who potentially meets the same end as Ash (Ridley always said he wished he could redo the Ash death scene A possible sex scene in Prometheus that was storyboarded for alien but never shot The ship getting destroyed at the end and them escaping in lifepods A rumoured 'Dark ending' such was Ridleys original idea for Alien Even the transparent Alien Ridley first wanted Its all here in Prometheus, the alien DNA he talks about is the Space jockey set/spacecraft. Theres even more if you look into it. What are your thoughts?
