I don't think it's acceptable to throw your hands up and say 'no one knows' when clearly people have spent entire careers thinking about this stuff and testing it in experiments, and plane-scale educational techniques. We're far closer to 'knowing' than at any point in history, and true knowing is a philosophical topic anyway without a satisfying 'answer'.
