Athiest

Definition
An athiest is a person with no invisible means of support, who watches a Notre Dame versus Mustangs football game and doesn't care who wins. Paradoxically, according to G.K. Chesterton, if there were no God, there would be no atheists.

Organisations
Many atheists join non-prophet organizations such as the Church of Atheism in UK andthe First Church of Atheism in USA.

Problems
The main difficulties with atheism as an unbelief system are (a) they have no holidays and (b) when things go very right or very wrong, there is no-one to thank or to blame.
