Well you don't have to if you don't want to, I don't really care weither you do or not, its your life. I just choose to look for a meaning. The point of my living. I do not accept that we live to die. Not looking for something cuz it has no proof is closed minded. Explorers found North America whent hey thought the world was flat. They took a chance of falling off the edge and look what they found. A little enlightenment of the world around them. They could have been like you and choose not to look for riches and hold back on exploring because of death by falling off the edge but they didn't. They had no proof of that land but they found it.
