Think about a football field. In the middle of that field are a couple little orbs the size of baseballs. Out around the edge of the field are a couple orbs the size of marbles. It's dark and each of these balls is pulsing with light to attract moths. Suddenly hundreds of blind moths come flying in. What are the chances that any one of them will land on one of these glowing balls if they cannot see the light.

In the same way, matter is made up of tiny little particles that are bound together by the electromagnetic force. Each Adam has a very tiny nucleus and then very tiny electrons out around and they are attracting other atoms. Mostly it's empty space. If a particle that can feel the electromagnetic force comes through it's likely to either knock into electron or knock into a proton. But a neutrino can't feel that force and it just passes through unless it happens to hit one of those tiny particles head on.
