Agreed.Not necessarily. It’s perfectly possible that the physical laws within the universe (such as cause and effect) don’t apply to the universe itself. The whole thing is very difficult to even think about given were talking about concepts like “before time” and “everywhere in the same place”. Ultimately, nobody knows though in the scope and scale of our lives, I’m not convinced that fake makes any difference.
A little difficult to define reality scientifically since science requires separation from The topic for objective validity. If science cannot create realistic separation from the topic then scientific statements about the topic are darts at best. You can't be both the car engine and create an objective external schematic of the car engine at the same time that's impossible. Although everyone lives to pretend!!!!!
