This brought up an interesting theory about their collection of human DNA, bio-material..etc.. As humans have evolved we lost physical strength, our
teeth become smaller and more blunt, and brains however got larger.. If we follow this through to an alien species that is much older and more evolved
than us, their descriptions make sense.. large head (to accommodate a larger brain), and very small mouths, some described as just slits. Advanced
aliens obviously do not need to grind their teeth on a steak, they most likely don't eat meat, and or maybe not even solid food at all.
Perhaps they have evolved so much that their bodies have become too frail, and they are not very hardy beings.. this would explain why the aliens
aboard the crashed UFO in Roswell died from the impact.. you'd think advanced spaceships would have some safety features that would prevent death
from a crash.. but if their bodies are physically weak as they appear to be.. then they can die easily from blunt force trauma.
Maybe they want to use human genetic material as some sort of possible DNA modification to increase their physical hardiness.
