For years and decades, archeologists and historians have been studying on the remained relics of Indo-European people. Their efforts were continued by the attempts of linguists to recognize Indian-European race and their primary homeland. This study concentrated “Andronovo” and “Jeyhoon as two ancient cultures which here identified as Indo-Iranian. It poses this claim in discussion that during the late 3rd millennium B. C., these tribes have probably separated from Indo-European tribes which settled in the steps of Eurasia. During late 2nd and early 1st millennium B. C. (Late Bronze Age), they continued their way towards the southern parts of central Asia and Afghanistan. These people after separating of the other tribes entered northern India and Iranian Plateau. Avesta, as the main historical evidence of the Persian language people and particularly Gathas, are our main textual source to become aware of the Arian people. It includes this people’s memories of their original land which they called it Aryanəm vaējō. In this research, an effort has been done to determine geographic situation of Aryanəm vaējō through investigation in findings of archeologists and comparing it with the text of Avesta and less Rig Veda.
