Why the upper planets can’t be perceived

Telescopes and the other imperfect instruments of scientists are inadequate for evaluating the upper planetary system. Although such instruments are needed because the vision of the so-called scientists is imperfect, the instruments themselves are also imperfect. Therefore the upper planets cannot be appraised by imperfect men using imperfect man-made instruments.
