A few questions I would like answered if anyone can fill me in.
Why did the Engineers leave maps on Earth, through the various cave drawings and such, for 35000 years to a planet that turned out to be a military installation?
Why was it that if an Engineer drinks the black goo they create life, but when a human drinks it they become a zombie? Dr Shaw confirmed we had the exact same DNA as the Engineers, not similar, the exact same.
Why did Dr Shaw give birth to a facehugger?
Is the Alien we saw at the end the Queen from Aliens? Why did it have a weird mouth?
Why were the Engineers going to destroy Earth?
Why was the medical machine, one of only a dozen and one of the most expensive machines in the world, only work for men?
Why did the Engineer immediately attack the humans upon awakening? He was asleep for 2000 years, so last known contact with us we were on horseback and using bow an arrow. He wasn't a little bit curious about how we managed space travel? How did he know we did not have a fleet of space cruisers orbiting the planet?
Why did we not have a fleet of space cruisers orbiting the planet? Or at least one? When Chris Columbus found America he had soldiers with him and multiple ships. Would it not have been prudent to have some kind of back up on the off chance you do find the space traveling "Gods" and they are happy to see you?
