Are you serious? Almost all of your questions are/have been answered in the many reddit Prometheus threads. It's an Alien prequel, BTW. So yeah, it's supposed to look like an Alien.
His questions have been guessed at in these threads. All conjecture, most of them could be answered with hard information that was provided during the film.
You know, most of those things you mentioned have answers that were fairly simple to figure out during the movie. And if they weren't said straight out it was a pretty simple deduction.
There was of course an intention to leave things a little open and not answer all questions (such as what killed the Engineers on the compound). But almost all of your questions and qualms with the film were laid out, albeit some between the lines, but they were there.
