In my opinion thats exactly why aliens probably will not evolved into anything like us. Some assume that life can only exist in an M class with conditions similar to earth. Who is to say that ther will be similar conditions on other planets? Perhaps life doesnt even evolve as carbon based. We have no idea what kind of life is possible.
While i do believe in the possibility of aliens, I think my best friend said it best.
