Why are people expecting to see ufo's and aliens?

The world we see is not the only world around us. And the worlds that people claim to see are not necessarily the same worlds. There are many physical worlds with different densities, many planes, realms and dimensions. Those who hope to see an alien or a flying saucer with their physical eyes are going to see squat. Those who do see them are lucky. Those who would like to see them will have to tune into their various wavelenghts or vibrations. Yes, it will take some effort and adjustment, but those who are looking at the sky day in and night out, will not only end up with a sharp pain in the neck, but are also of the same species who hope to see Jesus appear on the clouds in human form of all things. What could be more ridiculous than that?
