They aren't. But a digital camera is not a naked eye.
. Nothing I've read about them gives me the notion that they are visible to the naked eye.
I'm wondering what pictures they use to base their assumptions off of.
When you can show me a legit picture of a cosmic ray I will acknowledge you.
What do you expect to see in them?
I look forward to those pics.

All over the place:
Typical "cosmic rays streaks" can be detected in the dark or during the night. These fast particles hit the camera and leave a "streak". They need the DARK to be detected with a complex subtraction of intensity and manipulation of that particular frame.

Your statement is false. A cosmic ray is able to saturate pixels at day or night and it requires no processing for them to be visible on a digital image.
As I said in the post above:
It turns out that both cosmic rays and glinting rocks are pretty common on Mars. They've been spotted before. Such rocks have been seen in images sent by several of NASA's Mars rovers, and cosmic rays appear in images that Curiosity sends to Earth each week.
