Who is ramming who?

Did you pay close attention at the ramming sequence, or better image? I see above all, the saucer and right behind it, from what I can sense, the derelict, which feels to have a bad intention towards the saucer (maybe trying to ram the saucer for whatsoever reason) and Prometheus is clearly struggling to ram the derelict. Why? why? why? Explanation: The Gods (saucer), beings with good intention and of upper hierarchy in creation, probably benevolent and with the intention to maintain the balance of life throughout the universe,have already punished the sjs for trying to steal their technology of creating and destroying life in the Cosmos. They are the keepers of the planet in question and have neutralized the sjs. The sjs, are lower hierarchy beings but somehow higher from us. They hide in the planet LV, but knowing that their days are numbered, they execute a devious plan to regenerate their species annihilated by the Gods, by setting the pictograms trap. As Prometheus arrives, their plan is on the way. After the entire mess, we feel we are going to watch throughout the film, takes place, somehow the Gods are unaware of the rebirth of the sjs, and as they leave the planet, thinking that sjs are cleared and balance in once again restored in the universe, the derelict launches, in order to ram and destroy the saucer and then it will assume full control of the universe the Gods formerly possessed. Prometheus crew realizes that and executes a heroic attempt to stop the sjs, whatever the cost. What do you think of that? Hey? Ok...don't shoot me!Just enjoy the ride!:)
