    I feel like there is also a lot of a certain bias(selection bias? Observation bias?) i cant remember the name of. Basically, human sites inside of caves SHOULD be the thing we find most often because they are less likely to be eroded away. Whereas human sites that were right next to a river are much more difficult to find because the river has expanded, eroding away most of the evidence. You are left with small artifacts instead of paintings, fire pits, bone collections, etc.
