I love how you guys are all so open in your mind set about the world and the possibility of life on other planets but you're all forgetting one thing when you talk about there being no need for a cover up because nobody would care, the rest of the world isn't. You seem to all forget that human beings are the most egotistical, self indulging creatures and to suddenly and dramatically be told that we are no longer special and that we as a race may even be in fearer to another race would be devastating. Suddenly huge questions about society are front and center, like are states, or countries necessary, do we even need localized government, what does it mean for differences in society if we are no longer the supreme species, or even just the only species(some of these are assuming there is more intelligent life not just micro organisms). Not to mention the HUGE religious impact, organized religion is proof of human beings obscenely vain nature and would be severely undermined with the knowledge of life forming or living on another world. Think about it, almost all major religions say that a GOD created us and made us rulers of the beasts and all that crap, made us special, what do you really think would happen if we were no longer special? Seriously, you guys need to think a little broader then the suburb of some U.S. city, undeniable evidence of life on another planet would have huge repercussions throughout the world. I know some of this is a little over the top but there really would be major implications for life as we know it because of how NOT open minded we really are as a species.
