Exactly! An excellent read is "Who wrote the Bible" by Richard Elliot Friedman. Sorry if I have repeated what someone else has said - don't have time to read through all the posts.
IMO, if an intelligent God existed then he would have communicated his existence, intentions, the meaning of life etc etc., in a clear and concise way that left no doubt whatsoever. The fact that he is hasn't shows that he either doesn't exist, or doesn't care.
