Why do so many scripts exist around this area?

Saw this info on another sub earlier. Wonder if there are any reasons why so many different scripts are in use in that region? Eight if including Hebrew from a bit down south.

Which one do you find the coolest? Which one of the non-Latin scripts do you think is the most difficult to learn for Latin script users?

P.S. I heard that Persian are basically Arabic script with some modifications. I’m not familiar with both so cannot explain further
