Why do people assume that aliens require mechanical devices to travel? [View all]

We humans tend to create beings in our own image such as what we did with the old Greco-Roman gods, the Norse gods, the gods of the Incas and Aztecs and the divine beings of the Abrahamic religions. Religion gives meaning to that which we do not understand. Thus aliens are highly advanced creatures who travel to our Earth in pimped out versions of our own spacecraft or the spacecraft of science fiction novels.

Ever wonder why God has a throne or why Heaven has rooms or why angels carry trumpets and swords? Maybe because the people back when the books of the Bible were supposedly written could understand a throne, a room, a sword or a trumpet. Today some believe in aliens visiting Earth in spacecraft as most everyone understands spacecraft.

UFOs could be non-intelligent, earthbound phenomena. They could be highly advanced aliens' who, over the course of millions of years, have evolved into pure energy and they zip around at fantastic speeds through multi-Universes and in and out of our dimension. But humans like to create beings in our own image and thus many believe aliens to be humanoids from other Earth like planets who travel in highly advanced spacecraft.
