A man ay become an aheist because he found out his wife wa scrwing the custodians of two holly mosques

There are many motivations for explicit atheism, some rational and some not. Explicit atheism may be motivated by psychological factors. A man may disbelieve in god because he hates his religious parents, or because his wife deserted him for the neighborhood minster. Or, on a more sophisticated level, one may feel that life is futile and helpless, and that there is no emotional room for god in a tragic universe. Motivations such as these may be of psychological interest, but they are philosophically irrelevant. They are not rational grounds for atheism.
