We should have a better definition for the word hole
Like... In my opinion, a hole is when it does not go through, and when it does, it becomes a tunnel. A straw is a tunnel. A hole in a piece of paper is a tunnel. A bowl is a hole.
Technically there are multiple Through Holes in the human body: the mouth to anus, and the lacrimal puncta. Watch the video to get educated by the biggest beard in the world. ( https://www.youtube.com/watch?v=egEraZP9yXQ )
Holes don't exist. It describes a location that lacks the material surrounding it. Kind of like coldness is lack of heat or darkness is lack of light. Cold and dark aren't actual things in the universe.
