The Archons, / Greys / Reptoids, all seem to need this controlled agenda for what is inside the human.
Hmmmm. Imo, trying to fathom out reasons can get tricky and a lot can only be heresay from others, what feels possible / makes sense.
So my personal view is that, because I feel we are not a 'pure' physical species in many ways, maybe what we are Now is something unique or required in some way by other entities, or even that the Earth, whom I believe, like the planets and possibly other Cosmos 'inhabitants, are Living Beings, by controlling 'us,, the forces of Earth can be controlled for their whatever purposes.
I also think that we are, in the main, a two in one entity, a species that abides in this 'human' body and the 'original' species itself, and we are still tryng to keep in balance as a norm state.
Other writings say that some entities are spiritual parasites and they need from others what we produce spiritually / chemically.
Also something to do with having to keep humanity ( and maybe other life forms) in a state of non-realisation of what they really are and what they are truly capable of.
I have come across many ideas but of course can only think on them as possibilites.
What with mass information and dis-information these days and the discrepencies from many that obviously have had contacts in one form or another with agenda situations, well, it's hard to work out even a preferred reason for alien intrusions.
I am drawn to the Gnostic writings, as I have been for many years, and I cannot say why, and these writings seem to indicate a 'fear as food' policy.
The Archons do come across at being very successful in mind manipulation and that indicates they are still very much involved in the Now.
A pretty awesome subject.
