Can we be even sure that earth (and everything else from universes to ourselves) exists in the first place? Maybe we are just very complicated simulation faking it? Is or can we possibly have any strong proof for it? Stronger than Occam’s razor for example.
This is the "brain in a vat" thought experiment in philosophy. Also the simulation hypothesis.
In short, I don't believe it's falsifiable or testable. We can just reason about likelihoods.
Relevant to this is solipsism. We also don't have and can't have specific evidence that another being is conscious. At best we can just say that it's likely that they are.
Yep, just saw it also. This speculates that we are fake. My curiosity is whether it is possible to prove or falsify it.
Descartes had quite strong proof that we do exist (cogito...), but also he was not able to say are we real, or what we really are.
