To be honest, I think it will definitely happen in my lifetime (in the next 70ish years)….It wouldn’t surprise me if something has been found already and its just not in the general populations best interest to know about it at this point in time.
If the collision of ETs and humanity pan out like Stephan Hawking suggests, I for one think that it will be Karma biting human kind in the ass for all the pain we have brought upon our own planet and fellow earthly inhabitants. And if they treat us with respect, and help us into a new era of technological advancements beyond our wildest dreams, I think we should all thank our lucky stars that a species much greater and fairer than human beings found us.
I think it will eventually happen, and it will result in either the evolution or extinction of human beings….either scenario is exciting in my opinion.
Or maybe we are not even interesting enough to poke a stick at…thats always a possibility.
