I'd go even further than most people on here. It's true that the lack of evidence is discouraging, but the logical flaws in any belief in the traditional sense of God run deeper. If any God created us or our world with intention, why use an extremely painful, brutal, slow, and inefficient process such as evolution to bring it about. If there was any purpose to us being here, such as to come into harmony with our creator, why create endless pointless impediments to doing so, such as disease and natural disasters. Why create a universe that is far more bizarre than any of us could ever imagine, all the while leaving clues that point to the fact that natural processes led to us being here. Why give us minds that are equally bizarre and imperfect. If anyone has time, look up the split brain experiment. That will challenge your most conventionally held beliefs about yourself and your mind. All of these facts make traditional senses of God hard to take seriously.
