Is there life after death?

Watch and listen to survivors of the Lazarus Phenomenon (you can watch the entire documentary film halfway down the page): http://thetruthshallsetyoufree.wordpress.c...rus-phenomenon/

In the words of Albert Camus:

"I would rather live my life as if there is a God and die to find out there isn't, than live my life as if there isn't and die to find out there is."

Why is it necessary to believe there is a God? Just live your life without superstitious mumbo jumbo. We should be able to find happiness within... not through a man made product (i.e. the Bible/ Koran etc)
