Atheists pride themselves on their rationality. Most claim that God has been debunked by science, and in particular by Darwin’s theory of evolution. There is no need for a creator, they say, mankind was not created, humanity simply emerged from the slime by the process of natural selection among random variants of earlier life forms.
And if you ask these rationalists where the primeval slime came from they tell you it arose through the chemical and physical processes that in the course of billions of years shaped the earth, its climate and oceans.
And if you ask them where the earth came from they tell you it arose through evolutionary processes in the galaxy, involving star formation and supernova explosions and stellar nucleosynthesis and other events occurring over the 14 billion years since the birth of the universe in the Big Bang.
And if you ask them who set off the Big Bang, they tell you it was the result of a quantum fluctuation in the vacuum.
And if you ask them who created the vacuum and who wrote the rules that caused this Mother-of-All quantum fluctuations to occur in said vacuum they tell you, um, well, we’ve not yet worked that out, but obviously it wasn’t a being in the form of a man with a gray beard, who set the thing going solely for the purpose of creating Planet Earth and its residents amazingly evolved in the image of the Creator.
