"Hindu cosmography, for example born in hoary antiquity, strikes one in certain ways as surprisingly modern. India has never limited its conception of time to a few crowded millennia. Thousands of years ago India's sages computed the earth's age at a little over two billion years, our present era being what is called the seventh Manuvantra. This is a staggering claim. Consider how much scientific evidence has been needed in the West before men could even imagine so enormous a time scale."
