Heres the thing....

There are some, that are made by man. You can tell because the wheat is broken near the bottom. ITs dead and doesnt come back.

There are some that are unexplained, and cant be replicated, becasue the wheat isnt broken, its bent, and still intact, and ends up standing back up and growing after. And out of these ones all of them reflect some sort fo natural pattern and or sacred geometry

So id have to say its both ( which isnt in the poll )
