What are the oldest known tombs that can reliably be traced to a person? These are surprisingly tricky to track down. While archeologists constantly find human remains at an excavation site, there are almost never any identifying marks about the person. This is particularly true in the ancient world. Other than massive sites like the pyramids, we have little knowledge about the final resting places of famous figures. We don't even know the burial site of Alexander the Great -- the biggest celebrity in antiquity.

In this episode we talk about ancient tombs, crypts, mausoleums, and burial mounds. But more broadly, we look at how humanity's understanding of life, death, and commemorating those who passed away left behind more than tombs. It may be the reason for the rise of civilization itself.
