"Oh yes he does". In the post of yours that I quoted earlier, you suggested that one doesn't need to be as intelligent as Einstein to believe in god. That is a poor choice of words because, not only did Einstein not say he believed in god, he specifically said that belief in a personal god is childish.
In other words, your post would have made sense to reference someone of intelligence that was a theist, whatever their definition of god was, not an agnostic in the belief of a higher power and a true disbeliever in the belief of a personal god.
...and that is misleading. As written, it would suggest the person believes the existence of a higher power is more probable than not. I could equally write it as "to be agnostic is to believe that it is possible there is no higher power". An agnostic would believe that, with the knowledge we have at hand, and potentially into eternity, one could not prove either way.
