One of the many objections we as Christians bring up in opposition to an atheistic worldview is that life cannot have purpose. If there exists no creator, no one that created humanity with a specific design with a specific purpose then we cannot go on to say that life has any real purpose or meaning. In the end we must simply eat, drink and be merry for tomorrow we die and there is nothing left after that.
Atheists object to this point saying that they can create purpose themselves. They can create purpose by creating their own goals, their own wants and achievements. But does this really amount to anything?
