this has been brought before but i dont see any reference here on the engineer page
the fact that the one from alien is basically....5 to 10 times larger than anyone on prometheus, while it migh have something to do with "perspective" i mean, how would it look an feel if they were that big?, some scenes would be weird also the sets would need to be way bigger, everything would look out of place and even some scenes in prometheus would be just ridiculous, but the fact that there is such a difference shouldnt be left without explanation
i have a theory, we humans have people that are 1meter tall and some that go up to 3ms being 1.5 more or less the standar size, being the engineers the precursors maybe, they dont have genetical flaws associated with their size discrepancies, thus, they can have literal giants without being any genetical defect or illness associated to it, and fusing with their own suits and even technology, MAYBE, having adaptable "control chairs" could be perfectly possible, so a pilot that is that big(alse we have to take in account that the inside of both their ships and the temple had actually more space than they actualy..."needed" to move in, so maybe is something that exist, also, while all the holograms showed "regular sized" engineers as well as the upcoming movie....background ones...maybe is something thta isnt commn but isnt a problem and is actually taken in account by their civilization, and again, having bio-mechanical technology, adjusting it wouldnt be as difficult as we mighthave in here
another theory, given that they have genetic manipulation skills(black liquid, the xenomorphs and so on) maybe they have enhanced engineers, and mybe that was the case with the one from the first movie
or a third one that woule be a mix of the above, bigger( but not as big as the alien's) get their unique traits/advantages enhanced genetically?
what do you think?
