@blairmrachek It sure looks like you're not alone. There's a whole thread over on Reddit of guys complaining of very short drops that cracked the back glass on their Pixel 8's.
It appears that the "official" Google response to broken glass is to replace the enclosure; basically the entire frame that houses the rest of the components of the phone. Here's the Google repair manual showing the procedure; as expected you'll be gutting the entire phone and transferring everything into a new frame.

The good news is the enclosures are readily available; you can buy the genuine Google part right here on iFixit.

Of course the intent is for you to buy the one that matches the color of your phone, but I can't see any reason why you couldn't just pick any color you like at this point.
For those of you who are balking at paying almost $150 USD for the enclosure and are looking for a real challenge, it appears that it is actually possible to replace just the glass in much the same way it's been done for iPhones for the last several years; you carefully pick the broken glass from the rear of the phone then glue a replacement glass on in its place. I ran across a video showing a guy doing just that on the Pixel 8 Pro, although I don't know if there are any significant differences between the 8 and the 8 Pro.

For those of you who don't want to sit through the whole video, basically you're chipping away the glass at edges to start with. Once you've gone all the way around, you're left with the NFC/Charging coil that's glued to the rear glass. So it becomes a major pain in the a$$ to separate the coil covering most of the rear of the phone and being careful not to damage it in the process. The video spends several frames on checking the function of the charging coil at pretty much every step along the way.
The glass itself also looks easy to get; here's an example of the first one I came across being sold on Amazon.

In summary, it looks like the choices are between a painful repair involving an expensive part that requires gutting the entire phone, or a difficult but inexpensive repair that risks damage to the NFC/Charging coil if you aren't extremely careful.
Let us know what you find and what you decide! Good luck either way.
