It’s actually impossible for anyone who lived before the time of Prophet Mohhamed to be a Muslim
That’s like saying Adam was Zoroastrian
Don’t forget the PERSIANS were Monotheists before the Jews and Arabs they believe in One God then the Jews stole the idea and then the Arabs stole from Jews
Does this mean Zoroastrianism is the True religion because it’s the first “ONE GOD” Faith in the whole world certainly NOT because A God has to be a God of the whole world and not one People.
But... the Polytheist perspective is actually quite better it says There can be Multiple Gods one for the Persians one for the Greeks One God might as well be Completly wrong
It makes more sence cause never IN HISTORY has Humanity with all same BLOOD have worshipped the same God!
This means there is multiple Gods and many Gods throughout history which is more PEACEFUL then shoving your monotheism down Peoples throats.
Instance God of the Jews Israel and God of the Arabians comprises 5.3B of the world Ofcourse your ancestors didn’t worship The God of Arabs cause there is no such thing Elaha is the Semetic God Of YISRAEL whole Allah is God of Arabian Who recently convert to ONE GOD in muhammed time’s, before Muhammed ARABS worship STONE and have many Gods
