the Aryans inhabited the Arctic region

According to SB, the Arctic region was inhabited by the Aryans long time ago. When the Glacial Age came, they were forced to migrate to the South, most of them to India. Arctic region has long days for about 5 months and short days for 5 months and full days for 2 months. For those who died during the long bright days, i.e., Uttarayan period, the rituals concerned with the dead could be carried out conveniently, whereas those who died during the 5 months’ period of dark cold and short days of Dakshinayan, had to be buried till the bright months started. So everybody had to suffer during this period. That is the reason of this conception of going to the sun (heaven) or to the moon! But this tradition continued from one generation to the other, till now, in India also.
