It’s a bit like asking if solid walls exists. You say of course I can see one right there, but then I say but the walls are made of molecules, which are made of atoms, which are mostly just empty space. Therefore the wall isn’t really there, just empty space with nuclear forces acting to prevent us moving through that space.

Does it matter that everything is made of quarks which are probably just energy and that when you dig into the components walls and the air are the same? Or does the illusion of the wall fulfilling the purpose of a wall mean that walls are real?
