Which is the Biggest Religion in the world?

I think it's more important what you have in your heart and whether you're kind or not than to believe in the words that were written by other people, though you can find really important and honest ideas in different religions' dogmas.

 

humanity is the biggest religion in this world nothng else

 

I think its hinduism, and all other religions emerged from hinduism itself.

 

IT WOULD BE........... Christianity because of Catholicism.

 

If you look this by the oldest religion then Hinduism is the oldest and it is the Biggest

 

offcourse Christain is the biggest religion.
