Actually, if this was the intention then it would definitely be the creation of ALL life on Earth, not just mammals, since all animals carry ~99% similar genetic code.
Possibly, sure. But...what about trees, moss, grass and so on? You only mention animals...but life on earth is more than just animals. What about plankton and seaweeds?
Not that it really matters much, it's just a fictional movie and all. In that scene though, was it NOTHING but rock and water? Or was there any moss on the rocks?
Dr. Shaw seemed to have issues with getting pregnant by the "boyfriend" (mentioned before their sex scene and when on the op table with David). Could she be a human clone? We never saw or knew about her mother (from memories seen by David).
I don't think so: were she an android, would she be “infectable” or able to breed the alien hentai beast?
On the other hand, were she a clone...what possible reason would there have been for her creation as a clone? How would that add anything to the story?
Just because she has no memory of her mother doesn't prove anything, there's lots of non-clonned people who don't have any memory of their mothers, who may have died in childbirth, or shortly afterward, say in a car accident. Meaning, while there's no proof she's not a clone...there's also no reasonable reasons to think she is, either.
There are two different groups of "Gods", the "creators" whom spawned life on Earth (different looking ship (saucer-like)) with Scientific/Spiritual goals and the "Spartans" (Bitten doughnut-like ship) with the intention to defend their civilization. It could be that the "creators" spawn life around the universe and when their civilization find a threatening species evolve then they send out the "Spartans" to cleanse them out from existence in a Bio-friendly way that give way to the next clean beginning (they mentioned that dead "Spartans" dated only 2000 years which coincides to when Humans sparked with technological progress).
Why? Because one ship was a disc, the other a horseshoe?
I'd expect that there might be a different shape spaceship developed 60,000 years or millions of years later, especially if the ships were for different purposes.
It's plausible that the race of “engineers” would actually have many different professions, as humans do. But they wouldn't be genetically different from each other any more than truck drivers are genetically different from bankers.
On the LV-233 seemed to be a planet full of these bio-weapon "silo" and one of them could been of different types.
I don't know about “full of them” all over, but there was 3 of them specifically right in that area...and it's plausible that there were many more bases around the planet, maybe even on other planets in the system too. Like maybe on LV-427. Which might or might not be in that system.
Did the "creators" go back to Earth and visited early humans to show them NOT to go to LV-233? But Dr. Shaw and Dr. Holloway
misinterpreted the illustrations?
Maybe...but then why would they tell them the star system location in the first place? What would be the point of giving them a precise star map, if to tell people a 300k years earlier “don't go there dude”.
What exactly did David say to the "Spartan"? "Did you brush you teeth this morning?"
“Give me and my boss more life!”
“How do you do, I'm David, human cyborg relations, I am fluent in over six million forms of communication, and can readily...” SNAP!
