So, he hits the back of his head and smashed BOTH eye sockets and you think this is a normal fall? That’s not critical thinking.
BASE of his skull. Not back. Read the excerpt. Now do you actually know what the BASE of a person’s skull is? Lucky you we’re on the internet:

Oh look 5 bones make up the BASE of a person’s skull. One of them is called the Ethmoid bone. Wonder where that is?

Oh isn’t that interesting, it’s at the roof of your nose and between the orbits. Geeze right there in eye socket area.
The base also includes the sphenoid, which is on the outside of your eye socket.

And the temporal bone slightly behind that.

So actually there’s a lot of ways you can break one of those and eye sockets. Really one good face plant that hits up high can do that.
Really, try out some critical thinking. Also reading comprehension would be good. It would help if you actually understood the difference between back and base.
