Share, I was thinking along the lines of life, including the existence of human beings, as a reflection of the abundance of life in the universe. If this is so, then what are the mechanisms for making this happen at such disparate places. Perhaps the holographic theory of the universe may be true.
Also, even if we can detect the existence of humanoids in these exoplanets, is it possible for us to communicate with them or even visit their worlds? At this time, our technology is not advanced enough to make this happen.
