[b]I Believe.[/b]
i'm a christian too. but i believe.
i believe that WE live before with different identity.
then, we live again in another body.
i believe that we've been alive billion and billion of years ago,
but we don't have any memory of that because we are [b]reborn.[/b]
also, in an anime i saw

, souls of the dead travels in a dark cave continuously because that travel in a dark cave represents your rebirth in another body.
like that.
