i have no doubt that there isn't life outside our earth.
its to fucking greedy to think otherwise..
universe has no age, has no limits, no end, no start. the human brain cannot comperhend that because everything we know has a start and end.. it is hard for humans to understand that there is nothing beyond nothing out there, the universe is not big, it is not small either, my point is there is no size which means there are endless numbers of planets out there... some where out there, there are suns giving off enough light and heat to the soild rocks orbiting them, which has the right mix of everything needed to make life. it happen with our earth, why cant it happen elsewhere? no end = no limits.... there IS life outside ours, give me a good reason why there cant be.
and yes, even if it is bacteria, it is still life
