Along with Islam and Judaism, Christianity is a semitic religion with direct ties to Natufian racial origin and mythology. These Natufians are ethnically cousins of paleo-europeans, who's genetics are now a minority share in European people, after the Yamnaya expansion westward.
Aryans are the name that the Yamnaya gave themselves, well, the word in proto Indo European was Hwerios, which became Aryos, then Aryan in ancient Persia and India. (Indo-aryans from this time had little or no dravidian admixture).
Examples of religions with Aryan ethnic ties are: Nordic paganism, Greek mythology, Roman mythology, Zoroastrianism and even Hinduism, which is the only one that is still alive in large numbers. Semitic (Natufian) religions have taken the most prevalence in the world.
The listed Aryan religions are connected through a common ancestor, but some are distinct. All of them are polytheistic except Zoroastrianism, which has the one God Ahura Mazda (the wise one) but has something like demigods who are "people worthy of worship".
All in all, Judaism and it's clones are the dominant worship systems in the modern world, meanwhile more and more people fall out of the grips of religion and convert to atheism
