Although I can technically accept that god might exist, I believe that the chance of him actually existing is so infinitesimal it's not worth consideration. There are a million things that more logically explain things before you get to god.
I also don't believe that life is meaningless because of the absence of god. Nietschze's beliefs explained how this is philosophical error pretty well:

Stanley Rosen identifies Nietzsche's equation of nihilism with "the situation which obtains when 'everything is permitted.'"[10] Nietzsche asserts that this nihilism is a result of valuing "higher", "divine" or "meta-physical" things (such as God), that do not in turn value "base", "human" or "earthly" things. But a person who rejects God and the divine may still retain the belief that all "base", "earthly", or "human" ideas are still valueless because they were considered so in the previous belief system (such as a Christian who becomes a communist and believes fully in the party structure and leader). In this interpretation, any form of idealism, after being rejected by the idealist, leads to nihilism. Moreover, this is the source of "inconsistency on the part of the nihilists". The nihilist continues to believe that only "higher" values and truths are worthy of being called such, but rejects the idea that they exist. Because of this rejection, all ideas described as true or valuable are rejected by the nihilist as impossible because they do not meet the previously established standards.
