If we, with our puny telescopes and pathetically small radio telescopes, have found some planets from space around us that actually have water and reasonable climates, I believe there's no change life doesn't exist somewhere out there. We came to existense by chance, from a single molecule that was able to copy itself. Why wouldn't that happen somewhere else? I believe the chances of there being some other planet with carbon-based lifeforms are very, very high, and carbon might not be the only chemical element life can base itself.
There is someone ou there. You just wait.
Actually, I'm waiting for us to find bacteria from Mars. I really believe there's something alive there. Or, maybe not anymore, but definitely there was. Maybe we only find fossiles, who knows.
In any case, I really think the relevant question here is whether anyone has visited us or not. Frankly, I believe not, but you never know what the big, bad governments are hiding to get ahead of each other. I mean, science is in a serious lag, because even though military scientists come up with all sorts of new, useful equipment, they keep the info with themselves for 50 darned years before telling the public.
Thanks for ruining science, you military jerks. If someone really has visited us and they shimply shot whatever it was and then hid it, I'm seriously going to move away from this planet. ;)
...Wait... Ha, ha, I finally saw you here, Alakazam17 :laugh:
