religious zealots is enough proof that there is no god.
all those silly zealots doing their best to get gods attention - screaming out to god... LOOK AT ME, LOOK AT ME - but god does not look at any of them - but the zealots dont give up - and year after year, they keep screaming to their god - but god just ignores them.
there is something wrong with zealots - sure the holy books might demand eternal devotion, need to abide by the good book blah blah - but it is easier to control people, who believe in a similar faith
