It's nearly impossible to imagine what these people were experiencing as they explored these largely undeveloped and uninhabited lands here, in comparison to where they were coming from the food sources and land usage must've appeared impossibly untapped. It's interesting to think about how people would react today if an uninhabited island was discovered that just had many valuable resources, and how the world would react to that.

It's interesting to think about if these similarities emerged largely because of each of the civilizations influence on each other, or rather as a result of what types of food could be grown for example. Geographic particularities could've individually influenced each civilization, without any overlap from them to each other.
