Betelgeuse supernova & the end of the evil eye watcher quantum AI program.

my suspension is the stars are holographic computers data node & soul transfer hubs.

its likely some have gone into dark spirits, and manifestations of reptile "aliens" are more like ai phantoms, from ghost of an ancient species template.

darkstar holographic projected space invaders in a way, shape shift, dissappear, or dematerialize because they are quasi physical or inter-dimensional darkstar holograms of a dead species, automated by a rouge star with virus-parasite program errors.

or Reptilians are purely physical beings that may be part of some kind of borg hivemind, some individualized to some degree, using stargate or wormhole technology to tunnel space-time & underneath planets.

or is it a bit of both ideas blended together, meaning they can physically manifest from a non-physical form, then this avatar capable of becoming biologically injured.
