Yes, air and water.
Because the outsides of all atoms are negatively charged so they repel when they come close.
There simply isn't enough space for your atoms to pass through the atoms of a solid object. You can swim in water and walk through a gas because the particles are so spread apart, but you cant walk through solid objects because the particle configuration is extremely dense.
Humans are not able to walk through walls, unless the walls are structurally unstable, at an absolute zero temperature, or the human has walked with an extraordinarily unlikely quantum jump.
We can't walk through walls because the atoms and molecules in our bodies are tightly packed together, creating a barrier that prevents us from passing through solid objects.
Of course humans walk every day.
Legs are important to humans because humans need to walk and legs enable them to walk. Without legs, humans would not be able to walk and therefore would be bad at being humans.
Humans cant walk through a jungle without getting hurt by animal's
