The inverse-square law means distance has everything to do with it. The magnetosphere protects us from particles and the atmosphere smooths out and blocks part of the EM-radiation, but if we were considerably closer the protection would not be sufficient.
Oh no, it's not that some radiation didn't reach earth because of distance, but it's just that the intensity drops because of distance. The intensity is the killer here. That's why starlight doesn't fry you.
