David the real cause of SJ's anger ?

My first post. Great fan of the Alien series. I have been reading this forum for so long , finally joined today. I have been thinking a lot of what may have triggered the SJ's anger. So many theories have been discussed, though most I have felt not so convincing. After having thought a lot, I have a theory . Well, as per our knowledge so far, SJ's somehow helped man's origin. Hence they are the GODs for mankind They invited us via the cave pictures, expecting us to reach them when we reach a certain level of technology. I think they are more like reminders for man that their Gods live here, not just invitations for us. Next, the Prometheus reaches them. What they see ?? They see David, created by man. Means, Man has now become GOD - means knows to create something moving and intelligent. This irks the SJ's first up - out of pure ego or so. What's next ??? David is playing with the ampules, possibly which may cause another life form to emerge. I think whatever he did , lead to Holloway's and Shaw's problems as seen in the trailer. This fact is taken as a threat by the SJ's who are not ready to give up the life creating technology. Already they created Man, who then made David, who now may end up creating something else !!! So what to do next ??? Get rid of their own kids - man , so they don't make anything more, and also can clear the robots too. The reason of the anger being jealousy of the creator about his creation. Of course this all may be just be a wild guess. If already discussed, please feel free to lock this.
