hello,
        I found out that in google map, if you search "BIRTHPLACE OF BUDDHA" then it shows india.. so i would suggest every friend to visit this website : and do the change..  you need to sign with your google account and u can do it.. tell eveyone whoever u know. !!
and also on the right side u can see "For these and other reasons, report a problem." click on report problem and also write feedback and ask google to change it.. !!
