empty space is a misunderstanding of atomic structure. its an intersection of energetic fields, not a bunch of tiny spheres.

you would need the energy required to break coulombic repulsion, and to break quark gluon confinement [consult a. einstien r. oppenheimer]

A human body contains trillions of atoms that collectively form a macroscopic object.

For someone to pass through a solid wall, every single one of these atoms would need to quantum tunnel through the wall's atomic structure at exactly the same moment in perfect coordination.

While quantum tunneling can occur for individual particles, the likelihood decreases exponentially with the number of particles involved.
