Refutation of Nilesh Oak’s dating of ancient texts

Surya Siddhanta was NOT written over 14,000 years ago

Refutation of the article “Ancient updates to Sūrya-siddhānta” by Nilesh N. Oak and Rupa Bhaty

In an article in IndiaFacts and two presentations [1–3], Nilesh N. Oak and Rupa Bhaty have claimed that astronomical text Sūrya Siddhānta contains information that can be dated to 12,000 BCE. Oak and Bhaty have cited three astronomical observations from Sūrya Siddhānta that can be simultaneously satisfied only in 12,000 BCE [1]:
