That really depends on what is meant by 'Indigenous'

The old UN definition was a people with no stories of migration to the place where they now live .... As Fiann Paul at some point there were no Indigenous people - i.e. we are all from migrants at some point in time.

In today's world the term 'Indigenous' can best be understood in terms of it's pair - 'colonizer', i.e. the people who were there before the colonizers arrived. The colonizers largely being European, and the colonizing period being from Christopher Columbus reaching America (1492) to India gaining independence (1947).

This is way complicated by the migrations, invasions, etc etc , across Asia, before the Europeans arrived. And the actions of the English were certainly those of a colonizer.

Equally, the actions of various groups moving into India also look a lot like colonizers. So it gets very messy.

I would probably look back at the group now called Dalits as the oldest Indigenous people - though the label is not easy to put on Asian countries.
