Stefan Molyneux attacks this topic at his blog, Freedomain, with a tall glass of cold logic. You definitely should go read the whole thing, but I want to highlight a choice paragraph here:
If gods are subject to physical laws, then religion makes no sense whatsoever, and praying to gods makes about as much sense as worshiping a black hole, begging the Sun to grant you favors, or circumcising your son to appease the speed of light. If gods are not subject to physical laws, then the concept of “gods” is synonymous with the concept of non-existence, which makes religion even more deranged. Then, rather than praying to the moon, you would be in fact praying to the empty space between the Earth and the moon.
The italics are mine.
Stefan manages to make the logic of strong atheism engaging, and he has a clever way of pointing out the ramifications of silly god-based premises. Go check it out.
