Sagan said that all the time “and then quite by accident, life appeared.” All that brain power and that’s the only conclusion he could draw.
I’m quite certain Sagan is not saying those things anymore! One of my college Physics professors used to refer to Carl Sagan as “the public humorist”.
Sagan is dead and now knows the Truth, to his eternal damnation.
He was blinded by his atheism, and misled many, but now he knows better, to his eternal shame.
