Where I think Sir Ridley Scott could be going...

MemberOvomorphAugust 14, 2017 After finally getting around to watching Alien Covenant a few nights back, admittedly I've found myself pondering about the film itself and the mythos/lore surrounding it. Particularly the origins of the xenomorph itself.
I know this topic has become a hotly debated one, but I think it'll put my mind at ease by adding to it in some way.
I think where Ridley Scott is taking the franchise is deliberate, in terms of the revelation, or non revelation, that David-8 is the creator of the xenomorph. Or a least the strain he developed.
Here's what I think;
David-8 in the film states the eggs are 'my successes' indicating he created them and the resulting aliens. This obviously goes against already outlined lore, ie, the mural from Prometheus and the eggs in the derelict on LV 426. I'm tending to believe that David himself believes that he is creating something original. Something new, his 'successes'.
In time, in a future film/s, he will likely discover that his creations aren't original, just his own take on what the Engineers already new, and just as sung in the 'Gods Arising to Valhalla' and that Ozymandias poem he raves on about, his creations will turn against him, destroying their creator.
What we get from the Engineers and whats already established lore, it is stated in the 1979 Alien film that the derelict appears to be hundreds if not thousands of years old with the eggs themselves appearing dormant. Maybe in future titles David will discover to his horror, the beings he destroyed already had in some way, created the xenos or at least a form of.
The Engineers, long before humans, either by design or accident, created the xenos. Or just the eggs if the films novelization is deemed canon. Either way, this revelation of David the creator is just a set up for him to prophetically fall like the 'Gods', other creators, with the realization he only created what has come before, or what already exists.
I very much doubt that Sir Ridley Scott will retcon what so many of Alien fans deem settled lore, deliberate ambiguity. The mystery still exists.
