Siddharth was born in lumbini ... Gautam Buddha was born in India. Nepal didn't exist then. Nepal was unified by prithwi Narayan. Before then it was called "greater India " or "bhaarat barsha" with 100s of small states and territories (lumbini was one of them ). Swasni chodera bhaageko Nepal bata (bhaguwa) , gyani saint Bhako chai India ma ....so I don't really care
