Do you believe that there are aliens? [I Am Not An Alien]

I don't know about the basis for the Pentagon's report but I have no doubt there are aliens, but I question their ability to get here because of the massive distances involved to even the nearest star, there is also the question of timing, an advanced civilization existing somewhere at the same time we have the ability to know about them. But no doubt that there are other living creatures on other planets somewhere sometime elsewhere in the universe.
