I think it borders on insanity to say what cant exist in a universe thats literally too big to even comprehend. We cant even go look on the moons of jupiter that seem to be ice and may have water under it that supports life. how can we know what is and isnt on planets it would take us 50 generations to get to? thats not even considering the other few thousand or million galaxies with billions of planets each. I find it unlikely we are the only earth like planet in the universe. Hell id be shocked if we were the only ones in this galaxy.
