Please can anyone explain to me why things appear solid and the texture of things. Given that everything consists of atoms which are 99.999+% of empty space.

Electrostatic forces keep things from actually "touching" each other. Solid/liquid and the various textures of things are a result of the molecular structure of objects. Metals, for example, have a crystalline structure that is very rigid at room temperatures whereas water molecules slide freely around each other.
