I want to know the answer to the following question:
By what era was India inhabited by humans of some form?
All the background I'm provided with is that "Isolated remains of Homo erectus in Hathnora in the Narmada Valley in central India indicate that India might have been inhabited since at least the Middle Pleistocene era, somewhere between 500,000 and 200,000 years ago.". Is that enough to answer the question?
Answer: yes
