So let's review...

The large stones in history were moved by normal guys who had to work hard to move them.

The large stone you posted a photo of is tilted because they cut it out that way so it would help start down the hill when dragged.
The book of Enoch is quoted by many church leaders in the past ,yet none of them teach it was inspired and should be on part with the bible.
Other none bible books are also in the same way quoted by the same men

So the idea that the book of Enoch is part of the inspired bible is in error.

And....

The earth is round and goes around the sun....case closed.
