Let's say that somehow we were able to verify irrefutably that there were extraterrestrial beings en route to our planet. (When I say "we" I mean the entire human race) We know we have exactly 10 years before they reach the Earth for some unknown purpose. Do you think that we could - as a species - get our shit together in time to face the potential of this new threat? Or would we simply continue to argue and fight petty wars until the aliens came and possibly wiped us out of existence? Please discuss.
