Why Do People Get So Upset When The Vedas Are Described As Mythology

“The froggish philosophers and mundane wranglers in science and mathematical calculation may not believe in the inconceivable potency of the Supreme Personality of Godhead, but they are sometimes puzzled by the wonderful jugglery of man and nature. Such jugglers and magicians of the mundane world are actually puzzled by the jugglery of the Lord in His transcendental activities, but they try to adjust their bewilderment by saying that it is all mythology. There is, however, nothing impossible or mythological in the Supreme Omnipotent Person.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.6.39 Purport)
