What did the ayrans do most commonly for jobs? (i'm asking because i have to do a song for social studies)

(i think you mean Aryan?) The Aryans had a agricultural lifestyle which was widely established by around 1000 BCE.  Aryan settlers cultivated some wheat and barely but they were primarily horsemen and cattle herders. However, the Aryans were led by a hereditary king and were divided into five major tribes. They remained warriors. They fought against non-Aryans and fought one another. They even persuaded non-Aryans to help fight against other Aryan tribes. War itself was described as the “search for cows." This is all i can find but I would suggest you also google it, you can find alot of articles about them.
