in this franchise, i think the only prequel i would want to see is the 'engineers (is that what they were called?)' presence on earth millennia ago
david's summation that ancient Sumerian was the closet language to theirs was intriguing.
i could give shitzless about any sequels
Um, to do that would only clash with known science and would piss a lot of people off. No, these "engineers" did not create Humanity nor did they seed the earth with DNA. In fact, Scott invented the Engineers after the fact, because H.R. Giger's original alien pilot in the ship they found was what they saw sitting in the chair. Not just a suit.
The reason the Engineers were created and why the Alien story is being retconned is because Ridley Scott has an agenda.
