So I'm confused. If some specific relatively small devices (relatively to the size of the Earth) managed to pick up several of these over the years, surely some of these are hitting people? Are people randomly feeling like they got impacted (if not punched, as per a sister comment) out of nowhere? Apologies if this is a ridiculous question; physics was always my weak suit.

If you got hit by one of these then you wouldn't feel anything. The energy is about 50 joules, or about 1/2 of the heat that a human body produces in a second.

I wonder if it would kill a flea, or barring that, a bacterium.

Earth's atmosphere and magnetic field prevents these kinds of rays from reaching the surface of the Earth.
