I'm pretty sure its never been stated on the show at any point the Pagans are that old. And I question where this time line is, as Super-wiki is a fan wiki which includes articles on fanfictions. They haven't killed that many angels, and the ones they have are normally through stabbing them in the back with an Angel blade. They've also killed a lot of Pagan deities, and I don't see why being in India would make any differance.

Now that on the other hand sounds like it could happen, after all the angels were willing to negotiate with the Pagans over the world of God, how exactly the pagans would be able to help I don't know, but its still possible.
