does curiosity kill the cat?

After a thorough search and analysis of most all I know of this movie I've come to a realization. Our(meaning the members of this board) are under the impression from what Scott has said, that the jockeys/engineers created us. or that the life on earth was seeded by a greater power... I have no issue with this but what I do have an issue with is this....
SPOILERS(maybe) :
Why in the pluperfect hell would our creators feel the need to destroy us when we come to find them? If they created the human race(millon or billions) of years ago why do they feel threatened by us when we stumble upon the last SJ(I assume he is the last from script spoilers and/or casting spoilers)? As we see in the trailer the derelict(as I've seen it called) takes off towards earth? What do they(SJ's/engineers) stand to gain by going back to earth, presumably, for a second time?
My thoughts : As the trailers have shown us one or more of the characters is transformed by something(black goop, cobra thingy, eye worm... the list goes on). IF we assume that the SJ on this planet is the last of them, does going back to earth give it a way to repopulate perhaps? IF, changing the characters(holloway, and the mohawk fellow) some how turns them into SJ's as well, does the earth offer a back up plan to extinction? If not then why go BACK to earth? I don't see the connection...
an interesting aside : I have noticed a considerable amount of "prometheus" talk as of late. and its correlation to the movie. if it's simply a name, or more than that? does the story of prometheus play any role? one of the things I know is the idea of prometheus spans several cultures(who had no contact like we hear in the trailers from holloway and the picto-grams), christianity, islam, egyptian mythology, to name a few. they all speak of mans beginning and its roots in "clay"... each of these genesis stories refer to the fact that man was made of clay by a higher being.
in my mind I see the word "clay" as the element carbon, I've had debates with professors about this actually. The primitive understanding of life then was we all came from the same "stuff"... and that stuff is carbon.... all life on earth is carbon-based. does this mean all the life we encounter in the movie is going to be carbon-based as well, jockeys included? or is the interaction with the non carbon-based lifeforms what causes the transformation of the characters? What would actually happen if we encounter life based from another element? If the jockey's are not carbon-based then what is the point of visiting earth? why create people in the first place? If we breathe oxygen and they(whatever they are) breathe something else, whats the draw to earth?
Just some wild theories and conjecture from this guy...
