Christianity came to India in 52 A.D That is way before America was found.
And now there about 25 million Christians ( 3% of the total population) since then ( calculate the years )

 Now find out the numbers in Nepal since 1990 how many of them were converted to Christianity:
There should be a low anyone converts people to any other religions is illegal and punishable.
However the dollars were flown to Nepal from Various Churches and Maoists were the one who got the first instalment from churches.
It is not stoppable and from 20years from now people will start destroying temple and will be replaced by churches. As we have heard the threat of bombing Pasupatinat.
