Is there intelligent life on other planets?
The Great Pyramids, crop circles, Stonehenge are but a few examples of unexplained structures and signs that maybe, just maybe, we’re not the only intelligent creatures in this universe.
It’s true that scientists haven’t discovered any clear signs of extraterrestrial intelligent life (not that we know of, at least) but this doesn’t mean there can’t be intelligent life outside of earth. And even if we did find some being just as intelligent as humans are, if not more, would it even be possible to recognize them with just our human senses?
