Depends on your religion, if you have one. I personally don't because I see it as a waste of intelligence. There is THOUSANDS maybe even MILLIONS of other life forms out there, we are just a small speck. In the future, I see our goverment competing with other goverments for who can get out in space the farthest. Kind of like "Finding Nemo" where they're out on the drop-off and Nemo touched the "Butt".
