Whats next for the engineers? *SPOILERS KIND OF

So I finished watching the movie, and as the movie was good, the engineers were hardly in the movie. The only thing you see related to the engineers are the dead bodies, the flashback, and the hall of heads. Ridley Scott can explain it anyway he wants, or maybe not even at all, but from my take on it, and from what I have been reading, the engineers showed in the movie are not actually engineers, but are actually humans. As you see, the world they went to was labeled "Paradise" by Ridley Scott himself, and by the bible this means this world was the Garden of Eden so to speak, the origins of humanity. It makes sense since these engineers seemed very primitive in comparison to the true engineers, and worshipped the elders like before, with the hall of heads being shown in the movie. So that begs the question, what is next for the engineers? My opinion is that the elders and David clash in one of the movies, as David keeps labeling himself a god, and the movies keep referencing the elders as the true god (as they are god in the bible). I think the engineers have to make an appearance in the coming movies, and should have a bigger role to play. What do you guys think? I think this is a very important question as ALL of Prometheus had to do with the engineers, and AC seems to have thrown them out a bit.
