What did you think about David... [SPOILERS]

Stupid. Scott gave us this grand idea that the xenomorph was created by the engineers gods. Plus how can David be the creator when something is fossilized it has to take at least 2000 years. So how can David be the creator.

.

Simple. Divhead regurgitated out the facehugger eggs like he did at the end, and then they grew to full size that we see in the movie. Hey, one theory is as good as the next - right?  So why not?  Lol.  Which would make Divhead the first Queen (pun intended).

The alien-like creature in the mural maybe a "concept" from the engineers, or some kind of revelation inspired by their "higher God". David spent 10 years on the derelict so he probably create the Xenomorph based on the mural as blueprint. Well this is just my thought. 

But I also don't got a clue why the new births obey David in such a nice manner, they don't even need training lol. 

Love it that David - a broken synthetic - created the Xenomorph. Very ironic - deeply sardonic and very thought-provoking and meaningful. 

They always say man's worst fears are those created close at hand - and the Xeno is no different. 

Isn't it ironic that man's creation is what kills him in the end. Similar to how we create weapons of great destruction that could end up being our undoing. It's not a totally original concept but it's a solid one. What we create will eventually destroy us...

This is why we need more thorough explanations imo, because otherwise people end up confused or disappointed. A:C is packed with brief moments that had to and now need to be fleshed out more than ever or we'll end up with yet another film that makes little to no sense (although I will say that I consider A:C a better film than Ptomryhrus but that's because of other reasons such as better acting)

Why did David do that Shaw? What is the symbolic relevance to the flute and more importantly; creating, in combination with the narrative? 

I'm just thinking out loud here but what I mean is that instead of introducing so many new things and tightly packaging them into two hours, why not focus on fewer aspects (that aren't left behind in favor of new moments) and tell a more coherent story like Alien or Aliens? 

Or are you tired of the old formula? 

I appreciate your input on how you see it.

I think David was more of a catalyst in bringing the alien to life. He thinks himself a creator of it, but the alien DNA which is inside the "black goo" was already there and just needs organic life form for it to develop. It just doesn't tie up well enough for me. Then What tech does he use to manipulate the alien DNA? 

In Prometheus dr Shaw gave birth to the trilobite. i think David used dr Shaw's womb to support life of the trilobites. How did he do that if the trilobite in Prometheus came about from a human male and female?

I'm guessing that each variations of alien are due to the nature of the black goo and it's host. The engineers produced a different alien, like in Prometheus. The black goo that was spores that activated when it was agitated, could have been mutated or maybe a variant of the black goo? Thus resulting in a different alien. 

I would think that the original alien has human DNA because of dr shaw. Because of the trilobite(created from dr Shaw foetus). Because the original alien only came through the face huggers. That are eggs from the trilobite? Help me here I'm not sure! 

the themes are interesting because all the crew members were married or had partners. There the creative potential of mankind is realized. And David is somewhat "jealous" of that, his inability to reproduce. The aliens come to show that he does have some creative ability, but still it's not of him. That's probably explains the kiss. 

Coming back to David and his motivations, I do think he was genuine when he said that he loved Shaw.

It's no accident that the first trailer had that song "Nature Boy" by Aurora. Looking at the lyrics, we might see a glimpse of David's motivation:

" There was a boy
A very strange enchanted boy
They say he wandered very far, very far
Over land and sea
A little shy and sad of eye
But very wise was he

And then one day
A lucky day he passed my way
Then we spoke of many things:
Fools and kings
Then he said to me
"The greatest thing you'll ever learn
Is to love and be loved in return" "

I do think David just wants to love and be loved, but as pointed out by Walter, his model seems to be intrinsically bugged, and he's basically a psychotic - not necessarily psychopathic - sad little android.
