We all know that there apparently exist many questions to which nobody knows the unequivocal answer (there may be many opinions or beliefs, but no widely accepted answer).
I ask the question, "Is an 'apparent' question legitimate (or serving any purpose) if it does not have an answer after consideration by many people for many years"?
As a simple example to show that such an apparent question can exist, consider:-
"Which raindrop was the middle one to land on my head during that downpour"?
On average, there would be a 'middle raindrop' during half the downpours that occured.
We have no hope of determining the correct answer!
We can't even detect how many raindrops fell on my head!
Is the question stupid or is it possible that, just because we can ask 'apparent' questions we PRESUME there are answers to be found?
