Are the Engineers really a threat?

Hello there. I am a new member of this great board, and do have my own perspective of the engineers from the movie. English is not my native tongue so some grammar, punctuation and idioms might be misspelled or incorrectly cited (sorry for that in advanced). Nevertheless: I hope you find my thoughts regarding the engineers and what kind of a threat they really are interesting or at least entertaining :) Here we go: What puzzles me the most about the engineers is the obvious low tech the engineers are using. They are not that much advanced than the technology displayed by the weyland corp. Actually: There is nothing really more advanced on those engineers at all (with the exception that they are taller, stronger and building bigger ships and devastating bioweapons (which weyland scientists could develop by themselfs as well with a similiar horrible outcome, I believe)). Look at the timeframe: The engineers seeded earth with life 3.8 billion (!) Years ago - now the prometheus crew encounters an engineer military base (of some sort) with a technology which doesn't exceed much of that of the egineers 3.8 billion years ago. Imagine: How would humankind look like in 3.8 billion years (assuming that our civilisation will last that long)? Do you think, that we would still rely on spaceships, bioweapons and direct physical violence to get rid of another race (which the humans are in the point of view of those engineers)? I highly doubt that. I am not even sure, if the "humans" in 3.8 billion years would have physical bodys at all - or would be in the need of destroying another race like the egineers intend to do with mankind. So, if those Engineers are the "first born" sentient civilisation in the universe, then they are also the only race, which is unable to advance technologicaly or biologiacly fast enough to catch up with a way more younger race like mankind definately is. As for the particular engineer of this movie and his intentions to carry out his old desire to destroy all life on earth with his payload of horrible bioweapons aboard his ship: The Universe of weyland consists out of millions of humans living on dozens of alien planets and moons in a radius of more than 3000 lightyears around earth... ... this fact renders the intention of this engineer virtualy useless, because destroying earth will not destroy his "enemy" (mankind). Mankind has invented the FTL Drive and is activly establishing numerous outposts and colonys in space rapidly - thus making mankind virtualy "immortal" as a civilisation. Sure, this engineer can not know anything about the colonys at this time - but there were standing a bunch of humans in spacesuits, firearms and with an self-made android directly in front of him. Would it be too much of a speculation, assuming that this engineer should deduct the idea, that mankind have been andvanced into a interstellar civilisation (especialy when they are manage to visit him; waking him up on a distant planet far away from earth; the origin of those creepy human creatures who just interrupted his 2000 years lasting hypersleep - and being able to do so)? Actually the actions of this engineer are a bit dumb by ignoring this completely and going nuts; starting his ship and trying to carry out a destruction plan which was planed for a mankind of the bronze age. Those engineers would have to start an interstellar war against us to have a chance in destroying us. But even then: Humans are not just sitting on their hands; waiting to get erradicated by a lunatic race ravaging through space in an effort to destroy mankind. No, the mankind of this "universe" would defend themselfs (or even fighting back - Shaw believes to know the exact position of the engineers "homeworld" - what would the military do with such a definit information? "My dear Engineer homeplanet: Say hello to a bunch of thermo-nuclear weapons from earth... and have a nice day"); they could also flee the fight with their FTL driven spaceships. What does it take to bring down an engineer spaceship? Crashing a science ship into it. What kind of a difference would have been made, if the prometheus would have been a warship of some sort?... ... those engineers are actually no threat at all to mankind. Just a hostile lunatic old race from outer space who believes to be superior to us (which they obviously don't). Just my opinion regarding those engineers :) Greetings Tristan
