We often contrast ‘believers’ to ‘nonbelievers,’ but that can be misleading. Everyone believes something, in the sense that they must assume some principle as fundamentally true. Atheist often fail to recognize that they are in the same boat as everyone else. A common mantra of atheist websites goes like this: ‘Atheism is not a belief. Atheism is merely a lack of belief in God or gods.’
But it is impossible to think without some starting point. If you do not start with God, you must start somewhere else. You must propose something else as the ultimate, eternal, uncreated reality that is the cause and source of everything else.
The important question is not which starting points are religious or secular, but which claims stand up to testing.
