I don't think they were really "scientists", I think they were mercenaries or corporate security whose job was to deal with our Creators if they got hostile.
Seriously? Did the crew of Prometheus show any ability to "deal with" a hostile alien race posessing technology far beyond anything we could dream of?
Let's not forget Shaw's mind-numbingly stupid "no weapons" line as they geared up for there forst foray into the temple.
The crew was incompetent in both security and science aspects.
