Can someone explain to me what the Iluminati religion is about?
It's not a religion but you would definitely get a better answer if you googled it than you will on here.
It's not a religion.Nor does the group exist anymore.
Basically they're the ones thinking about the world ending. The real story is they believe Earth spins around this radioactive oval and when it reaches the closest to this thing (forgot) the world shakes like in the movie 2012. Only some believe.
I think a secret society still exits. Take a look around you and look at our own government and their affiliations with terrorists.
There's a real history of this group, research it on line and decide for yourself what they were or are.
