My husband and his neighborhood friend witnessed an extraterrestrial being when he was 10 years old (I don't know for sure the age of the other kid, but he wasa similar age). They were riding bikes close to home on a dirt road that had a series of small hills along them. They were racing and all of a sudden both stopped dead in their tracks. In front of them, approximately ~20 ft, behind the next hill was an extraterrestrial staring at them.
They could only see from the middle of its face up- the rest of the face & body was hidden behind the dirt hill. My husband describes it as having a large head with white, almost translucent skin that he could actually see blue veins pulsating behind. It's eyes were huge and bright blue.
He and his friend looked directly at the being for about 10 seconds, then looked at each other briefly and quickly rode toward where the being was. By the time they got there, it was gone with no trace in sight. They then split up and both went back to their homes.
My husband and this friend lost contact but happened to see each other about a decade later briefly. My husband just asked him- "do you remember what we saw that day?" The friend looked off like he was uncomfortable and just nodded.
I know many people won't believe this, but let me vouch for my husband. He is a pretty shy man and doesn't like any attention on him. He didn't tell me this until we were together for close to a year already. He is a very no nonsense guy who is the opposite of a bullshitter.
We are NOT alone.
