Not trying to be a wise-butt, but it sounds like something from the outside hit it. Check your interior and bed for something that may have struck it.
I looked everywhere for what could have done it. My truck bed is covered. I’m still curious as to how the glass was all pushed forward.

The cab is a low pressure zone while driving at highway speeds relative to the air around the vehicle so it makes sense it'd be sucked forwards

This^^^

I would expect the wind force to most always be forward at the back window In such a situation. I had a couple of Chevy Avalanches and the rear window was removable. Each time I drove it with the rear window removed, the wind was always beating on the back of my head.

Auto glass will shatter. A car at rest hit with a hammer will mostly stay in place with just a small hole from the hammer head. The wind force on a shattered rear window would be plenty to push the glass pieces apart.

The tempered glass pieces are safer than say a bathroom mirror. I’ll start bleeding the moment I see that stuff on the floor.

a quick example for auto glass shattering.

But never underestimate the stupidity of a 12 year old boy with a new pellet rifle...
Happened to me years ago. Driving down a state highway (45 mph) when girlfriend yelled “sh@t” and then the passenger window exploded followed by a whole slew of obscenities about the little MFer. Pulled over. She was covered in glass but told me she saw the “little punk” pointing his pellet gun at us. Circled back but he was long gone.

I had a tempered glass coffee table explode. This was inside our house in the family room and no one was touching it when it blew. Small glass crumbles flew in every direction, some over 10 ft. away. I Googled the phenomenon and found a video on Youtube caught by a surveillance camera of a similar explosion. Nobody was even in the room when that table exploded. Other Google hits explained it is caused by impurities in the glass when manufactured and if so, it's just a matter of time until it explodes. Most cases happen to tempered glass on outdoor furniture that sees great temperature swings. Not at all the case with mine.

The Station Wagon Effect. A vehicle moving forward with an open rear window and one or more sides open will cause air to flow in from the rear. Your window shards were part of the flow. I can spot an ill informed boat owner by the position of the forward facing Dorade vents, if equipped, at the bow. As for that snorkel, oh never mind.

Glass. An extremely slow moving liquid, not a solid although we assume it is.

I would be interested to see what Jeep says about this as a warranty claim. I would guess they would claim act of God unless this was somehow a common issue. It may seem hard to imagine how a rock hit it but Murphy's Law is a bitch.
