The dating of Mahabharat war (to be 5,561 BCE) is decisively proved by Nilesh Oak’s scientific research. And is also true with the Ramayana dating (12,209 BCE). His books (When did the Mahabharat war happen, The historic Rama and Bhisma Nirvan) details out the Astronomical evidances that he used to estimate the dating. He also talks about corroborative evidances from many other fields like, Oceanography, Hydrology, Climatology, Geology, Sedimentology, Seismology, and so on.

Will add more details here soon …
