Modern historians are telling us that the place farthest from the birthplace of Buddha has preserved the most authentic date of his birth.There is simply no reason for Singhalese texts to be more reliable than Indian, Chinese, and Nepalese texts.Further, it is known that the lifetime of the Buddha lasted eighty years.Based on these shared records in Buddhist traditions and the information provided by modern Indological research on the coronation date of A"soka, one is able to infer the date of the Buddha, though still with some questions remaining.In my last article ‘Kumāragupta-I, not Aśoka, was Devānāmpriya Priyadarśī of major rock edicts’, I presented evidence to show that Devānāmpriya Priyadarśī of major rock edicts should be identified with Kumāragupta-I of Imperial Gupta Dynasty, instead of Aśoka Maurya.This never before proposed identification of Devānāmpriya Priyadarśī unshackles the Indian history from the grip of wrong sheet anchors and provides us an opportunity to recreate the Indian history as it had really happened.He obtained his enlightenment in Bodh Gaya, gave his first sermon in Sarnath, and died in Kushinagar.
There is also evidence to suggest that the two masters, Alara Kalama and Uddaka Ramaputta, were indeed historical figures and they most probably taught Buddha two different forms of meditative techniques.
Various collections of teachings attributed to him were passed down by oral tradition and first committed to writing about 400 years later.
Scholars are hesitant to make unqualified claims about the historical facts of the Buddha's life.
The evidence of the early texts suggests that Siddhārtha Gautama was born into the Shakya clan, a community that was on the periphery, both geographically and culturally, of the eastern Indian subcontinent in the 5th century BCE.
According to the Buddhist tradition, Gautama was born in Lumbini, now in modern-day Nepal, and raised in the Shakya capital of Kapilvastu, which may have been either in what is present day Tilaurakot, Nepal or Piprahwa, India.
