Impact of religion on society

Most of the people in the world believe in god/s. Uneducated people believe that there religion is only true one religion, we don't live in middle ages.
In this thread I would like to ask you to answer what is religion to you.
To expand our knowledge of other cultures and people this is very important.
Only united human race will survive, united for the better future.
My respect to all religions,I love to learn new things.
