I mean for real, think about it. How can you honestly feel we are the only species out there? I do think NASA and other groups are closed minded as well when looking for new life though. Humans feel other life forms on other planets would have to be like us and live in OUR conditions and a planet like ours. I dont agree, I think life on other worlds if they are like us may not need to live on a world just like ours, Not need to breathe the same air, etc... But thats just me.
