The Lomas Rishi Cave on Barabar Hill. The Barabar Caves are the oldest surviving rock cut caves in India, mostly dating from the Mauryan period 322 BC 185 BC but these are likely much much older. This is hardly a new idea. In Egypt Peru & Bolivia, there are many megalithic works that were not made by the dynastic Egyptian or Inca people who academics insist were the creators, and this seems to also be the case in India. It almost looks like some sort of lava flow the way it is shaped.
