Sounds like people are making this into some religious conflict.
Look people. What you believe is yours.
What we believe is ours.
Live and let live.
It's as simple as that.
You have your faith, we have ours.
That is what liberty is about.
Seeing a relay on this universe being a simulation....
I doubt that,
because, simulation within a simulation and within, and so forth,
will inevitably occur, in a simulation where time and space is manipulated
and fast forward, energy and calculation restraints because of those simulations.
So... simulation would be designed to end at some point by the aliens...
If it is controlled. But again, unlikely.
Rather, seeing as particles in quantum entanglement isn't limited by distance,
this is a confined universe, in which the particles and atoms roam free, in its own free 'will', that isn't digitized, but tracked.
That is my guess....
