The AARP group seem to be really started by Humanist they have an article on George Washington and US History their version any way!
President Who? - The following historical documentation lends proof to the thesis statement that ten men held the office of US President prior to the inauguration of George Washington in 1789. The Journals of the Continental Congress (Housed at the National Archives in Washington DC) clearly prove the existence of a US Presidency by their legislative actions, resolutions, detailed recognition of the Presidency by foreign leaders and the actual formation of the office by the ratification of the Articles of Confederation.
