True Oniya, but that doesn't preclude the possibility we find life and either we don't recognize it or it doesn't recognize us. I could see perhaps the greatest hurdle in encountering extraterrestrial life would be communicating with it, whether it's a meso or extremo, since I can't imagine any other animal would be capable of producing the same sounds as we are. This thought is at least a century or more off, but imagine we encounter life out there, don't recognize it and then kill it? That could make us appear malevolent to a foreign life form no matter how benign or ignorant our intentions may have been.
Also considering the vastness of space involved expanding to other forms of life may also make it more likely to find extraterrestrial life in closer systems.
