For once, you're right. think about cave fish and cave frogs. they never see light and live in areas with VERY low oxygen content. An even more basic example would be a virus. damn near indestructable. modern medicine cant kill them and neither can lack of oxygen, light, water, air or even a host. The virus will just sit there for as long as it has to until it gets picked up.
and assuming there is a superior alien race, why wouldnt they pay us a visit? look at our space program, we go to different planets to try and learn as much about it as we can in order to help our own species. Maybe they're doing the same. Or maybe we are their proverbial ant farm. Its such a broad subject with so many variables that its impossible even to postulate an answer.
