OK, granted...it's definitely a possibility...likely even, but NO LIFE of ANY KIND has been found anywhere except this planet...how can they issue a valid degree in a theoretical subject?Because there's life on earth, which means given combinations of factors there is potentially life outside it.
I agree completely...but at this point, it's all just speculation because "there HAS TO BE life out there...we just haven't found it yet.""Life" is more than two headed aliens walking around. It's also bacteria and other simple organisms. I'm sure that's useful for something, but since I don't follow biology, I can't specify.
How can it be called a science if it can't be proven?There are many degrees that involve theories.
