"Thirteenth Floor"

I've read "What if our universe is a Science experiment on a shelf in an Aliens closet,with a rating of C-"?

Maybe?

Perception is reality. If you really think about it, it is all a simulation. It doesnt have to be for someones entertainment or control. Not a single thing we do really matters in the grand scheme. A billion years ago & a billion years from now, we were & will be stardust.

Man created god for many reasons, to explain the creation of the universe, to feel significant, to feel connected, to provide reason, etc. Many cultures created their own religion independent from each other because its not the god(s) that are real, but humanity's need to find or create answers. This same logic follows with the simulation theory, there is no supporting evidence yet the theory persists because of humanity, not because of a simulation.

However somewhat in line with the OP, who the fuck cares if it is? This is what I have now, make the most of it.

Whether any of that is true or not, has no bearing on our lives and how we live, so enjoy your life everyday and strive to do or cause no harm.

Food for thought

I dismiss anyone who posits that the universe is a simulation.

Sounds expensive.

Yeah the whole Matrix / simulation / brain in a vat thing is not actionable. What is true for us is what we have to engage with, so whether our reality is the bedrock reality is only of use as interesting speculation.

It does seem likely to me that our perception of reality is not that accurate in many ways, but how many steps removed reality is from some atomic baseline Truth isn't very interesting to me as it enters the realm of sheer speculation, the same place where supernatural beings and realms "exist".
