Unfortunately the article fails to understand the basic premise of atheism, which is that we no longer need to invent gods or goblins or any other magical creatures in order to compensate for ignorance. In previous eras so little was known that it was inevitable we invented explanations; today we have more adequate knowledge of the universe around us. Thus beliefs in gods, spirits, etc. is merely a holdover from former times; were these holdovers absent we’d have no impulse to invent them today. Atheism is merely the avoidance of a pointless regression that answers nothing at all.
