ELI5: Why do maps always start with North America on the left and end with Asia on the right?
gpt
Europe is in the center.

Since most maps were created in europe  (America was not discovered yet, there was an "europlean cluster" and an "asian cluster" of influence) during history, it became "common" in the european (and then american, since it was discovered by europeans) "tradition".

If you look at japanese or chinese (or russian) maps they are asian-centric for example.
