In third world countries such as Brazil, India, Africa etc. religion is very important as from religion they can make 'sense' of life. Religion answers: Who they are? What is their purpose of life? What is life and death? and many other question. In this countries science has not arrived thus religion answers all of these questions.

Other people follow religions (i.e. Buddisum) as they believe in their way of life. By this I mean although they do believe science, big bang, evolution etc. they also want to be vegetarians or do not want to have alcohol or do not want to gamble etc. So religion can be like a border line where the follower must not cross if they do so they will be punished in the going to hell in Christinaty and Jewism or having a bad karma in Hindisum and Buddisum.

But mostly religion brings people together for example, Chrismas or Diwali or any other festivals can be like an excuse where family meet (after long time), have fun and share memories as well as thinking and praying to God. Similarly it bring people in a community together.
