Firstly, the Illuminati isn't dead. Yes, maybe the evil Illuminati can be dead. Which I doubt, but the general Illuminati isn't dead. One of my football team mates father is a free mason. He's very open about it, and discusses it commonly. Illumnist's don't have too worship the devil. They can just be wealthy & powerful, and they can be in the public Illuminati.
Next, I have my reasons for believing the Illuminati is still in existant. Skull & Bones Society is still alive, which is a branch of some sorts for the Illuminati. Research it.
First of all, Skull & Bones is just a fraternity, there's NOTHING to suggest that it's got anything to do with Illuminati. And research it? I've studied about as much as the average person can study on it. And your friend's father isn't a free mason. The only members allowed to speak about it have to be granted permission to do so in an interview with supervisors there. If he was a free mason, he'd have more respect and not talk about it. Furthermore, if they found out, they'd boot him.
But seriously...
You want some background on the Freemasons? They were the remaining Templar Knights who were fleeing the Middle East, couldn't find safety in Europe, so they abandoned their arms and coat, changed identities, and boarded Spanish and English vessels to head to the
New World, America.
Savages, devil-red-skinned natives... wore face-paint beneath their black, evil, eyes. They were marked by the beast, as the beast.
To establish a "New World Order" was to set up government in the New World (America) and found a stable group of peoples to represent security (the aforementioned Templar Knights). They took upon a new name, the Freemasons. Break that word down... free, masons. They laid the groundwork of a country destined for freedom and democracy. They served to hold it up, support it, until it was stable enough to hold it's own weight.
But like every group, stories follow. The Templar Knights/Masons had treasures from the Holy Temples, even holding religious fortunes in the Chalice and the Ark, among other items of priceless value for which the country was established on and used to back it's worth greater than that which exists anywhere else in the world.
These treasures were never seen, found, claimed, etc., so the United States was forced to develop it's own currency and mint in order to create value based on other goods which would back it. This is where the theory gets deep, because if the Masons had this priceless treasure, why wouldn't they just use it to create a currency backed by pricelessness and dominate?
The reason was because they knew people would be lazy and turn to crime and try to overthrow 'em, so they allowed all of these mysteries to be fueled, hiding "clues" of their treasures on the mint so people would understand the great value and need for this new currency.
