Obviously, the distortion of understanding of All That Is can be done via education. As I mentioned great channeled sources explained in detail and were efficient in clarifying the distortion. To convince more and most humans, we need more factual information. There is a mystery surrounding Christ's figure and many other events and figures in our scriptures. The truth is known to you, please share it with us. Again, as I said, the best way of sharing would be to create a group of humans studying key questions. We need to assemble a group of best theologians, priests, historical scientists, allow them to see the facts, to integrate these facts in their worldview, develop a way of teaching the truth on the subject to mainstream humans using small practice groups and then start broadcasting the new teachings to wide audience using video broadcast on internet and later on television.
Obviously, these teachings would not be taken seriously or even noticed by masses at first. It would take months or years to build a reputation for the new off-planet broadcasting channel and to build the audience.
Obviously, there will be many attacks by the mainstream mind control agents on the channel, so it has to be made hacker-proof and should be able to sustain administrative restrictions. This is doable by creating many channels under one brand name. So if one channel (say YouTube channel) is closed, there would be many other YouTube and outside of YouTube channels which are open, so the listeners could easily switch to other channels. Same can be done on Television. The transmissions have to be of good quality to be able to enter and be invited and voluntarily broadcasted by various television stations. Creating these high quality broadcasts would require much of human talent and help from your technology.
Understand that humans would distaste intrusions by aliens. That is uninvited alien broadcasts would likely cause panic and rejection. On other hand if the broadcasts are done by humans, via conventional media and on competitive basis, it is a fair play and humans would accept it one by one, voluntarily. If an off-planet human broadcasting station produces good quality broadcasts and wins the audience, this will solve the problem.
