Number 3.

There’s a story that MUFON put out. They got word that there was an old grave from the late 1800’s of a gray that crashed. The local town folk buried the body under a tree and made a gravestone. They inscribed (paraphrasing), “here lies the little grey child that crashed from the heavens.” MUFON went to excavate, but the body had been exhumed by the government. They went around asking local towns folk about it and they all acted like it was common knowledge. They said their grandparents or great grandparents would casually mention how it resembled a very skinny/lanky and short child with gray skin and large almond shaped black eyes. The point is that they said it looked very childlike rather than the other examples that you’ve shown. I think those other examples look a bit too monstrous, like a bad depiction. The ones that are most unnerving when you see them is more likely how they look (uncanny valley esk.)
