If nothing in an atomic sense and literal sense touch how can we feel the difference between textures for example a tree and paper one is rough and another is smooth hos de we differentiate???

They do touch, actually.
How do you define “touch”? I’d say “to be close enough to feel the other object pushing back”. That’s what electrons do for atoms – when they get close enough they repel each other.
When you’re holding an object it’s the electrons in your hands pushing against electrons in the object via electromagnetic interactions.
