Is it a coincidence that out of all of Allah’s creations the greatest of them(the Ahlulbayt) happened to be in our universe
Like the ones Imam Al Sadiq mentions here

from Imam Sadiq (A):
"Perhaps you think God has not created a humanity other than you. No! I swear to God that He has created thousands upon thousands of mankinds and you are the last among them."
"Like this world there are 70,000 other planets with each of their peoples believing they are alone in the universe."
"I cannot say that there are human beings in other worlds, but I can say that there are living beings, whom we cannot see because of the great distance between us."
-Bihar al Anwar, vol 14, p 79

Everything is planned by God nothing is a coincidence. God chose for us to be in this realm
