Why Did Zoroaustrians Escape to India?

Shilanka was physically part of the indian sub continent at that time. The zoro astrians, the persians, or our pussian parse brethren and sisteren escaped from iran during the arabic invasion. There is no evidence they came through the sea route. They landed in inguja, in western india, in a place which is now called sanja sanjan - named after their home town of zanjan in persia.
