What is the proof that they have gone to the Moon? Why they are not now utilizing it, and they simply remain quiet? They have simply squandered so much money but there is no proof that they went. A foolish man squanders and does nothing and still we are to believe that they are scientists? According to the Bhagavad-gita, yanti deva vrta devan… without the necessary qualification, namely visa, etc., one cannot even go to another country what to speak of another planet, and the Moon planet, Candraloka, being a heavenly planet, how can we accept that they have gone to the Moon? Our point is that they are accepting foolish men as scientists.
