Rationalists even in India were convinced that Deities didn’t drink milk on the day millions of people saw it with their own eyes. Atheists will find many reasons to dispute that Krsna lifted Govardhana Hill. For example: how could He know where the Hill started? Why didn’t the hill break up as expected as it stood on one point? What held it together? Why didn’t at least some of the rocks fall off since Krishna must have tilted it at least in the beginning. How could He have found the exact center so that the hill could balance? How could He have put it back in the exact same place?
