Not all of them... Illuminati was founded on 1776 by an professor of university of ingolstadt, his idea was to explain world that everything can be explained by physics. Illuminati was cuted to 2 parts atheists and theists... The history of illuminati is too huge to let me write it here... The fact is that after illuminati were founded an other "group" called them zehists (I dont rly remember if this spells like that :/ ) which exist and this days. This group try to proof that juses wasnt exist and that were is all one stolen history... Let me give you an example: Egyptian god of sun (Ra) has exactly same history with juses, but as we all know Egypt are thousands years older than Juses.
Ra's story is simple, he was borned from an virgin, until his 30 we dont know nothing, he has 12 followers. blabla... I think this is enought to explain that Christian history is an big lie (a big part of them)
