Is it true that Lord Buddha was born in Sri Lanka? I've heard there's a rumor saying that lord Buddha was born in Sri Lanka and ancient "Dambadiwa" is not India but Sri Lanka. There's a "sal" tree in Sri Lanka which matches to the exact tree that we believe which was there in the birth of baby prince  "siddhartha" . I dunno whether they're true or not I just wanna know whether there's a truth behind it, whether what we believe so far is just a lie?! (Ps not Buddhism but the life story of Lord Buddha)
Lumbini, Nepal has been recognized as the birthplace of Siddhartha Gautama since a stone pillar was placed at the site by the emperor Ashoka circa 245 BCE.
