Wnat is the point of life in an empirical worldview...or how or why should I live my life as an Atheist?

You should not live your life as an atheist. From the atheist point of view, there is no point to living. Theirs is a dark and dreary existence with no hope, no true joy that transcends their current cirstances. Why go through life like that? There is peace, hope, true joy and comfort in a relationship with Jesus Christ.
