"Now, it would be ludicrous to claim that the IAs left the common Indo-Iranian habitat, as per the AIT, moved into Saptasindhu and turning the Haraχvaiti name into Sarasvatī gave it to a river there to remember their past while they proceeded to generate the root sṛ and its derivatives to accord with other IE languages. Occam’s razor, which here is conveniently ignored by AIT adherents, commands the opposite: that the Iranians moved away, lost the root sṛ and the name Sarasvatī in its devolved form Haraxvaiti was given to a river in their new habitat."
