Yes, I do believe in aliens, as it is statistically impossible for there NOT to be extraterrestrial life
BUT
I really don't feel like they would fly around in saucers watching us
in all honesty, there is a possibility that we cannot even see such things, as the portion of the electromagnetic spectrum we can see is TINY
And even if we could visually and audibly perceive them, there is very little likelihood that we would see anything familiar or recognizable about them. A race made up of sentient blobs is just as likely as a bipedal, or heck, tripodal race.
