There are unchallenged points. But a systematic scholarly well funded university program has be nurtured to really destroy AIT.

Language similarity between the European languages and Indian languages are major arguments for the supporters of AIT and the common origin. SInce philology and compartive lingiustics is an undefined science it will take several decades to descredit these unchallenged points.


Viable alternatives theories are in the initial formative stages. There are many but there is no unified theory yet.
The best theory is the genetic geographic mapping of genes from the southern asia to the eurasian and wider asian continent over the span of 100000 years.

Any new approach has to use this foundation and recreate the human civilization.
