>>9Therefore, our perceptions of space and time and existence and individuality etc. must be so flawed and limited as to be irrelevant. Therefore, eternity exists in some form.
Isn't there an equally-likely possibility of there existing no form of eternity, since our perceptions don't matter anyways?
If there is a ball inside a closed box, and I have no perception about the color of the ball, I can't make any statement about whether the ball is green or red, right?
If the ball is in a closed box, I have no way of being able to say "it's probably red", when my perceptions are so limited that I can't discern the color of the ball.
Isn't the existence of an eternity the same way? If the nature of "eternity" is in the closed box, and we have no technology to measure the contents of the box, then we have absolutely zero indication that there is anything in the box in the first place. If Bob says that there is an eternity in the box, and Alice says that the box is empty, we have no way of knowing who is most likely to be correct.
Therefore, with our current knowledge, it is impossible to say that either the existence or nonexistence of an eternity is more probable than the other, as we have no knowledge of what's inside the closed box. If we have no indication one way or the other, then considering both possibilities and their implications would seem reasonable.
