Assuming Einstein is right and nothing can exceed the speed of light, then why would an alien race travel however many light years (assume equivalent to light speed, then if 1,000 light years away, then the fastest they can get here is 1,000 years) just to exploit our resources?
This all assumes home planet = current location. Given a specie that is nomadic in nature and travels from one system to another, then they could be close by, and that would be a game changer to the above scenario.
