Have you ever had a dream that felt so real that when you woke up you felt as if you were still dreaming? Image if you were unable to wake up from that dream, how then would you be able to tell reality from fiction? If say, one object is erased from a system and the system continues as if nothing happened, how then can the other objects have recolation of the erased object? The absence of evidence is not the evidence of absence they say, if you have no evidence to prove we exist does not mean we do not, it doesn't mean we do either, hell, it doesnt mean anything.
I will conclude by saying, my friend, you are not real, neither am i nor anyone else here! We are all infinitely small blips in such an insanelly huge system that our existence is a mathematical impossibility of titanic propotions.
If anyone understood the above, please check into a mental hospital.
