I wonder why many people visualize aliens to be entities with flesh or something else like how species (that move or grow) on earth. I think aliens can also be in the form of new elements, rocks, gases, waves, or some entity which is beyond the ability of 5 senses of humans to perceive. Currently we use other methods to transform perception of entities so that humans can see/feel/hear/understand. But the devices we build for this purpose are built using earth elements. It could also be probable that earth might not be having those elements which are required to give humans the ability to perceive other entities.
