Which two world religions originated in Southwest Asia? Why do you think it happened here?

In the southwestern part of Asia or in the Middle East, two world religions arose:

Christianity. From the 4th century it began to be divided into such faiths: ancient apostolic churches (for example, Armenia became the first Christian state at the beginning of the 4th century), Orthodoxy, Catholicism, Protestantism. Jerusalem and the nearest cities became the place of origin.
Islam. It appeared 600 years later (according to their calendar, it is now 1396) in the west of the Arabian Peninsula, in Mecca and Medina.
In addition, Judaism emerged, which is not a world religion.
