My dear, , in a Srimad Bhagavatam Class on 18 December 1973 given in Los Angeles Srila Prabhupada describes how foolish the people are to blindly accept the theories of the material scientists regarding the source of the universe:

"Explosion. So people have no brain to ask that 'How this explosion took place?' When there is some bomb explosion, immediately there is inquiry by the police, that 'Who has put this bomb? How it took place?' But these rascals... One scientist says, 'First of all there was explosion.' But nobody will question, 'How the explosion took place?' Because they are śūdras. They have no brain. The rascal scientist says. 'There was explosion,' and he accepts. That's all. This is going on."
