I can only assume you mean Zoroastrianism. Zoroastrianism is a religion and philosophy based on the teachings of prophet Zoroaster (also known as Zarathustra, in Avestan). It was probably founded some time before the 6th century BC in Persia (Iran). The term Zoroastrianism is, in general usage, essentially synonymous with Mazdaism (the worship of Ahura Mazda, exalted by Zoroaster as the supreme divine authority).
It seems there may be a typo in your question, as "zoarasism" does not appear to be a recognized term. If you can provide more context or clarify your query, I would be happy to try and help you with the information you need.
