My wife and I saw a 10-foot-tall one this year. It was just a few feet in front of me. as our side door is just a walkway next to another house. Its head was slightly over the awning and while partially crouched its shoulder was at the top of the door frame. The Crouching Vegas alien video is not blender. That's a real alien. The one in the video would be skinny and the one my wife I saw was a muscular husky build. 1 peck was the size of my chest, its upper arms were very long for its size, "mid-forearm length for us if scaled". 3 very thick capable fingers. NO neck all muscle, I mean that, NO neck. huge mouth, canine teeth. I would have talked to it, but simple evolutionary theory is you have those features because you use them. IE: Birds have wings because they use them to fly. This 10ft tall praying mantis muscular humanoid with No neck and huge mouth canine teeth sharp teeth had evolved in a way specifically to powerfully grab prey in and bite. That huge head bites and tears the flesh from bone 1000%. Again it looked to me like it was NOT an ominvor or a species that cooks its food. Those teeth tear meat from bone.

sure these guys probably, currently DO eat things exactly like that or else they would not have canine teeth. if you don't use it, you lose it right.

Based on it's form they are brutal killing machines.

Yet I live on a mountain in Hawaii it must have not been looking when it hopped over a small wall that turns into a 20-foot drop because there is a tree in the way you can't really see it. so it falls into a bunch of my water jugs and the patio furniture making a huge noise. And when there is a loud noise I go outside every time, without fail 100% of the time. Then RIGHT outside there was a HUGE BOOM from this alien grabbing my hard luggage case and shattering it on the ground. For the first time in 8 years, my wife finds me frozen with my hand on the security door. it looks left and right turning its body to do so. It was actively blurry I had to rub my eyes twice.

my wife had to as well.

3 inches off center. But as it moved the details were visible. The Aliens head just above our awning. I learned my lesson NOT to look at aliens in the eyes. "they can freeze you in place"

So I didn't look this time. The alien ran away, my wife was in utter shock. As it happened when I was 13 and 16 I had seen and spoken to "greys" I am 43 so it had been a very long time and I had told my wife what happened as a teenager. She believed me, but when she saw it this year. she said it's different. I believed you but seeing it in person is a whole different experience. So we talked at length about what had happened to me as a teen. I won't bore you with what happened but
In conclusion, My incites are we are seen as a self-extinguishing race because of our individualistic tendencies, and being Non-individualistic is almost a prerequisite for space travel. As there are many many many different races almost 50. Spaceships don't thrust they slip. 10's of thousands of times faster than light. Learning WHY "not how " magnets work is the key to space travel. The ships move by magnetic shifting.
Our race needs to find out why magnets work "true space travel" before we nuke ourselves. Once we do that then we get to "go to school" with all the other young species. So basically not only are we not alone we aren't even allowed to go to school to realize we are the youngest kid in class. We might or might not get to that point.
sadly All 50ish species were Non-individualistic so at best I am sure we are NOT seen as viable or important allies. That's my TED talk lets go back to the white padded room.
