We can agree that pretty much everything and everyone was made or created by someone or something. We twenty-first century humans have figured out who or what made most of them.
For example, we all agree that the Andes Mountains were made by natural forces and the ruined city of Machu Picchu was made by the Incas. Why they built this city up there on the top of the mountains in Peru is not known (or at least not agreed upon), but at least we all agree it was human beings (not aliens!) that made it!
However, there are still a few origins that we haven't agreed on - yet. So let's debate them!
