Why do I think it has to exist??
Well based on sheer weight of numbers of stars in the universe and the discovery of planets outside our solar system its very possible that there is life scattered throughout the universe.
To me it is not a question of whether it exists or not but a question of whether there is a universal combination for life as in oxygen, water and a heat source (star) as well as DNA and atoms like here on Earth or can life exist in many forms. Think about a planet where maybe the inhabitants breathe methane or don't breathe at all for that matter. Where there is no surface and life there has evolved to be able to deal with the conditions.These are just hypotheticals of course as it could also be possible that there are just billions of earth duplicates where the combinations have come together like in our solar system.
I may sound arrogant saying "I know for sure" but of course I don't know 100%, noone does. Im only going off the vast weight of evidence pointing to this. I just find it very hard to believe that our planet is the ONLY source of life in the entire universe.
