Whole movie explained (MAJOR SPOILERS!)

Long post with a LOT OF MAJOR SPOILERS!! My view on the whole movie is as follows: 1) Engineers is granted with the gift of extreme DNA altering (black goo), either from another alien life form or through their own knowledge. Where they come from or how they know this is irrelevant. 2) Engineers look through universe after suitable planets that can sustain life similar to their own life form. "Earth" is found, probably one among many planets. 3) One engineer is chosen or volunteer to drink the DNA altering liquid (black goo) on earth to kickstart life in his own image. His ”pure” DNA is heavily altered and he is rapidly disintegrated. Engineer DNA spreads on earth. 4) DNA on earth creates life forms that become more and more like the engineers (human). 5) Engineers visits their "offspring" on earth on different occasions and is pleased. The "pre-humans" treats the engineers as gods, just as they expected and wants. 6) Visiting engineers creates marks (the five planets) to show the humans where they came from. It is not an invitation, just one way of showing their greatness to the inferior life form. Maybe one way of showing the heritage of the life form of this planet, if there are other ”black goo factories” that the engineers have. 7) Life on earth becomes more and more advanced, until humans are not so different from the engineers (like the "original DNA" left on earth by the sacrificial first engineer). 8) Meanwhile, the engineers on LV-233 are planning for another ”God”-journey to their planets off offspring. It is NOT a planned assult on earth to vipe out mankind. The black goo is NOT a biological weapon. 9) But just before take-off, something goes wrong in the engineers facility. Another small lifeform (perhaps the same earthworms as we see in the movie) is exposed to the black goo and speeds up the evolution-cycle. This new life form chases down the engineers, enter their bodies and killes them from inside. Only one engineer is saved, when he it put in the hyper-sleep chamber. 10) New life form dies due to starvation. 11) Humans creates new life form (AI and synthetic life like David) , and becomes gods of their own. 12) Humans find the five planets in caves, treats it as an invitation, build spaceship and travel to the origin. 13) Crew on Prometheus open door to the sealed chamber, changing the temperature and moisture. This makes the black goo come out of the containers. 14) Earthworms is exposed to the black goo and transformes them into the ”cobraliens”. 15) Cobralien kills Millburn by entering his mouth and bursting his chest. Cobralien accidently kills Fifield by acid in face. 16) Fifield falls DEAD into the black goo. This starts to transform some of the small organisms living in and on the human body (like bacteria, fungus and mites). Together these new lifeforms take control over the dead body, moving it around like a ”zombie”. 17) David gives Charlie a small amount of the black goo. His body starts to decompose (like the first engineer on earth) but also transforms other organisms on and in his body. Humans are not as ”pure” as the engineers. The worm in his eye is NOT the black goo itself, but a new lifeform. 18) Charlie has funtime with Elizabeth and some new organisms from him are transfered into her. This organisms inherit this genetic trait (growing inside human body). 19) Charlie is decomposing and his body is filled with new lifeforms. His life ends by flamethrower and takes it like a man. 20) Elizabeth removes the new lifeform, a facehugger-squid, from inside her with nasty surgery and takes it like a… woman. 21) Crew, with David and Peter Weyland, wakes the last engineer. At first he is surpriced and curious when his inferior children is standing inside his spaceship. 22) When David speaks to him in his own language, making questions about eternal life, he becomes angry. 23) The engineer discovers that humans are capable of making life on their own. David are capable of things that even the engineers cannot do. The engineer is furious because the humans has insulted their creator. He decides to kill the humans. 24) The engineer kills crew. Elizabeth releases the facehugger-squid which plants seed into the engineer. 25) A new lifeform, an ”Alien” bursts through the engineers body. This inherit some of the traits from the engineer, giving it head, arms and legs. 26) Some other engineers discover the new ”Alien” that have made eggs with facehuggers. They find the new life form interesting (maybe to use as a waepon) and decides to put the eggs on another ship and sends it away. But again, something goes wrong, and the pilot is caught by a facehugger. The pilot dies and the ship crashes on another planet. 27) The ship sends out a warning signal to other engineers to leave the cargo alone, a signal which Nostromo picks up in the movie Alien. What I cannot understand is: A) What is the meaning of the Alien-like statue or painting in the engineers big hall? B) What is the destination of the engineer ship with facehugger eggs? C) How and why does the first ”Alien” lay these eggs? I hope you enjoyed it. Sorry for long post.
