If atoms do not touch, how do germs attach to the atoms that comprise a person?

If man is made of spinning atoms that do not touch each other, how does a germ get into our bodies if nothing ever touches anything else....because as I understand it....nothing of matter is really solid,

germs are made of atoms, too. a solid. and atoms hit and touch each other a lot more than a gas. germs enter the body through a medium while hitting a touching each other. like a hit and miss. ramdom
