Rome never fell. It just morphed into the Roman Catholic Church.
Rome realized in order to survive, it needed to consolidate its cultic power into one solid entity.
First, secular scholarship had to be dismantled. The Romans accomplished this by burning the library in Alexandria and stealing all the books–which are now housed in the Vatican library. This, the Romans hoped, would guarantee that humanity would never find out its true origins or real history.
Second, radical religious men must consolidate their power, in the person of Cyril, Bishop of Alexandria who sanctioned the murder of Hypatia, one of the greatest classical scholars of antiquity. After Hypatia’s murder many scholars left Alexandria, as scholarship was soon to be persecuted and they could read the writing on the wall. The dark ages would soon ensue.
Thirdly, Constantine declared a Christian Conversion for himself, quite the politically expedient move, and Christianity soon became co-opted by the Catholic Cult, thereby once again consolidating the power of the Roman Empire.
Steven Greer talks about Jesuits and technology transfer, around 2:23 point in vid. He also mentions that around 2:42 point in vid, Hans-Adam von Liechtenstein, a Roman Catholic, is totally convinced of an ‘end times scenario’ and only funds people/organizations that support this endeavor in scaring the populace into believing this.
According to Greer, there’s a worldwide control group of about 200 to 300 members who’s sitting on these technologies and information. Not everyone in this group has the same ideas or agendas, but the most powerful faction within this group, who has access to all the technologies (mentioned is a spectrum of psychotronic weaponry, powerful supercomputers, advanced bio-science, craft with exotic propulsion systems and control systems linked to thought, and consciousness-linked real-time monitoring systems), is highly violent.
