As an atheist, I am often told by my theist friends how my perspective on life is bleak- that as an atheist, it is not possible for my life to have a meaning.
However, I feel that it is ridiculous to believe that the only way to have a meaningful life, is by believing in a being whose existence is only verifiable by ancient tales that have been passed on for years, or by believing that there is such a thing as an 'afterlife'.
Life is given meaning by the way you live it- not by your beliefs in a superhuman being.
It shouldn't matter whether you think that you will go to heaven, or decompose when you die to give yourself a reason to live. So live your life however you feel best- give your life your own meaning in your atheist(or theist) way.
