Give me just a little piece of archaeology, I can prove you that the god exists and I can also prove you that the God doesn't exist too.
Archaeology can be taken as proves for anything. Eg.: In 1920 and 1930's with the "archaeological record" Marxist archaeologist Childe proved that primitive communal societies existed. And with the same material, another archaeologist who inspired Adolf Hitler, Cossina proved the existence of a "herrenvolk". They both used the same archaeological data.
