Such questions as yours: why there is so-called discrepancy between the views of Bhagavat and modern scientists regarding the moon and other planets, and whether Hitler is good or bad man, these are most insignificant matters, and for anyone who is sincerely convinced that Krishna is the Supreme Personality of Godhead, for him these questions do not arise. Our information comes from Vedas, and if we believe Krishna, that vedaham samatitani / vartamanani carjuna / bhavisyani ca bhutani / mam tu veda na kascana [Bg. 7.26] that He knows everything, and "vedais ca sarvair aham eva vedyo vedanta-krd veda-vid eva caham [Bg. 15.15],'' that Krishna is non-different from Vedas, then these questions do not arise.
