The shot at the target

considering that the "target" would be the sun, it missed and hit earth instead.

To those who don't get it: light particles are emitted from the sun and are viewed by eyes

I dont get it. Can someone explain it please?

Look at it closer.
Look at the 2 last panels.

Wait I think I understand.
The moose sees the light particle coming right at him and the particle missed the sun?
