Ashoka stupa stands as a testament to where Buddha was born. And, there have been many more archaeological findings since the stupa was dug out that give proof beyond resonable doubt that Buddha was born in the area which falls inside present day Nepal. I've never said that Buddha was not born in Nepal - what I have said time and again is at the time of Buddha there was no area called Nepal as such. We are plain lucky that Lumbini, Kapilvasatu and other many areas of historical significance today lie within Nepal's territory. Why should I go to the UNESCO website to verify the truth about the location of Buddha's birth?
