I disagree. I am not an Atheist and I think if you (general term) don't believe in something like a greater force you have just as little of a chance of being right as theists. However, the Devil is in the details.
While I'm sure there are Atheists out there who are sure there is no God/Higher Force, my understanding of Atheism is that they don't believe in any known or purported God for lack of evidence. And if I understand correctly, the no-God determination is subject to change if evidence ever appears. In other words, their standard for belief is set at a higher bar than the average faithful who are willing to go with a feeling or what was driven into their heads as children.
Their mistake is the common Atheist habit of proclaiming "there is no God". While they may mean there is no God as "you describe it", a more appropriate response is "I don't know" what is there. Just because it can't be seen, does not mean there is nothing. I feel there is something, I sense something, but I don't like calling it God because the term connotates a sentient being of which we have knowledge of with a set of rules and expectations when in reality we no nothing, if it is an intelligent force that can relate or interact with us in any meaningful way during our physical lives other than what we imagine.
