[If this is all a simulation - like a computer game - does anything at all really matter?]

I think discussion of the simulation has to involve discussion of the nature of light 

We are told light is electric and magnetic fields vibrating in the nothingness of space. But the fields are said to be force fields. and the definition of a force is that which causes motion of matter (force = mass x acceleration -Newton) So space has to contain particles of some sort which move for the electric and magnetic force fields to exist. The ancient Greeks  knew this to be true and they called the particles the Aether , the 5th element. Light is motion of the Aether, the existence of which is denied by modern science.

 The double slit experiment gives a clue as to how the simulation works. When a light wave is passed through 2 slits the wave beyond the slits forms a diffraction pattern.

There are lots of videos on You tube about this. The videos go on to say that when the waves are 'observed' the waves become particles.- matter.  Never is it said how you can 'observe' a light wave. If you think about it the light would have to emit  light from itself  for you to observe it - that's impossible. What actually causes light to become matter , I think, is human consciousness and I have found the mention of this on the internet.

 

Our consciousnesses are creating the material world from another world which consists of light. We perceive our own bodies as solid matter when in true reality we are light beings.

 

 

[UFOs, Extraterrestrials and the simulation or Matrix]

I agree with David that we are living in some sort of simulation - the Plato's Cave - and are not seeing the true reality 

That being so I think we need to question the purpose behind all the information we receive through our senses 

UFO sightings are an example of information received and some or all might be 'holograms'  generated by the simulation

You might say they can't all be holograms because we are told some have radar returns.  But what we hear is just another part of the simulation -

or deception. And some or all of the witnesses may be deceiving us. 

As regards project Blue Beam - David says it is to unify people in the face of an artificial alien threat and to pave the way for a one world government.

But it may also have a another purpose - to create confusion- by projecting holograms of religious leaders and create uncertainty about a different sort of event.

Outside of the false reality we are forced into I do believe that extraterrestrials and UFO's exist. Inside our reality - who knows - I think maybe the dead aliens at the university of Ica in Peru are real and maybe the glowing orbs are something breaking through the Matrix to us.
