I want to know the answer to the following question:
How long ago are the earliest texts of Indian/Hindu philosophy dated?
All the background I'm provided with is that "The Vedas, the earliest texts on Indian philosophy and Hindu philosophy dating back to the late 2nd millennium BC, describe ancient Hindu cosmology, in which the universe goes through repeated cycles of creation, destruction and rebirth, with each cycle lasting 4,320 million years.". Is that enough to answer the question?
Answer: yes
