It has often and confidently been asserted, that mans origin can never be known: Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science. Charles Darwin
Here are a couple of quotes for you:
Romans 1:22 Professing themselves to be wise, they became fools,
Proverbs 26:12 Seest thou a man wise in his own conceit? there is more hope of a fool than of him.
By the way, how confident are you in Darwinian evolution being the way everything came about? So confident that a dissenting voice might upset the whole apple cart?
