It is my belief that we are not alone in the universe. I think it is the height of arrogance to believe that we are. Somewhere out there in the cosmos, the conditions MUST exist, as they do here on earth, that would sustain life.
Having said that, I will say that to have an alien form evolve over millions of years to wind up looking so very similar to human forms on earth is exponentially unlikely. I watched the video and I see a clavicle, vertebral bodies, pelvic bones, etc. and just have such trouble with it all. The clavicle is a very odd bone, one which is meant to lend support to the shoulder complex. This same bone developed in an aiien who comes from light years away?

What is the gray powder they speak of? Did they analyze it? I was sad to lose the English subtitles 2/3 of the way through.
