LOL, LOL, LOL
‘These people’ make me laugh.
LOL They just believe things, without ANY enquiry AT ALL. And, LOL no matter how illogical, irrational, and impossible they even are.
Some people “science” are far more ‘religious’ than some are in “theology”.
But there is NO such thing as ‘time’.
So, ‘Reality’ never has had to do with ‘spatio-temporal’, as you are assuming and asking here?
But anything can exist, in concept.
