Factual error: In the scene showing the two left-behind crewmen as they discover the snake-like alien, one of them reports to the ship that the creature is "30-40 inches long." The scientific community worldwide has been using the metric system for decades and it would seem highly unlikely a trained member of a starship crew would revert to such an ancient system of measurement.
Factual error: In the beginning of the film strands of DNA from the engineer are shown degrading completely and then randomly reforming. That way would be impossible to get similar strands of DNA which are implied in the film to be in our cells. Only through replication is a DNA strand able to divide into two similar ones.
Suggested correction: It was never explicitly stated that we evolved from the Engineers. We might just be some experiment they created from completely different DNA.
Factual error: When Shaw sacrifices the engineer to the alien she rolls out of the escape pod and lands with her hand and Holloway's ring showing. If the atmosphere was that toxic she would be dead and the suit would not be able to hold air pressure,.
Suggested correction: If the air is toxic, that doesn't mean she'd die from it right away. And the air pressure doesn't matter as it's been established that the pressure on the planet is about the same as what they are used to, or is in their suits when the other crew member removed his helmet before.
Suggested correction: It would be terribly unlikely for a trained member of a starship crew to do that. As it happens, he's not a trained member of a starship crew, he's just a hired mercenary.
