I believe we will find lifeforms of infinite variety. Levels of cognitive thought will vary widely as well. Even if we find exactly the same atmospheric makeup, we know that Earth supports a near-infinite variety of life forms. I do believe we will find ways of communicating with some of the life forms. I also believe we will find some more advanced than ourselves. We will learn from them...and they will learn from us. Whether any have already visited the Earth will be one of the most interesting findings. Although I hope we will find them peaceful, we must be prepared for any eventuality.
