To even think that an extraterrestrial species would be humanoid is to enormously underestimate nature's potential for creating body layouts. Even looking at earth will show that a bipedal configuration isn't even close to the most common or most efficient form. By sheer numbers, the primary species on earth all have six legs and an exoskeleton. Our body form is relatively well adapted to the conditions on our planet, but who's to say an alien planet is going to have comparable conditions to earth? There are so many different possibilities for life-supporting planets, the different biological forms we could see are practically infinite. Just some of the conditions influencing what a creature looks like are:
- Gravity (low gravity would mean taller and thinner)
- temperature (something adapted for a planet in a perpetual ice age will look significantly different from one adapted for a desert)
- food supplies
- surface conditions (water world, tundra, arid, or none at all)
I never meant to imply that all ETs were humanoid, and I would be surprised if there wasn't a great deal of variety out there. Dr. Robert Sarbacher said the ones were came across were more like clones and androids, specially designed for certain tasks in space and so on.
I only saw pictures of ones that looked like three of the small humanoids, and that's all I know.
There are even people who say that their craft are organic, biological and intelligent, or something along those lines, but I don't know that for certain, only what I saw.
