Are Chakmas of AP not indigenous people?

Indigenousness revolves around three important factors – primitiveness, vulnerability and time.  It’s a fact that once upon a time AP used to be vacant land. As time went by, people migrated there from China and Burma and thereby became native to AP and as well indigenous to AP. On the other hand, pre Partition, CHT was an integral part of India, therefore, Chakmas of AP have been indigenous to India since time immemorial. In fact, their migration to AP resurrected their indigenousness to India. To sum it up, the Chakmas have been native/indigenous to AP since the year 1964 , that is  for the last 54 years, while others have been native/indigenous to AP since time immemorial (probably for the last 200 years)
