“As far as I can discover from interviews with intellectuals and from reading books, there are 21 reasons many smart people find God unconvincing.
Here are the 21 reasons, bolded and explained:
God as an old white man in the sky is unconvincing
Depictions of God as a humanoid (this is called ‘anthropo-morphism’ = in human form) have been considered incredible since ancient times. Rendering God as a male humanoid is not credible to skeptics. Does this male God have genitals, a deep voice, facial hair? Also, it’s curious that God usually resembles whoever it is that’s depicting God—and that’s men! Men made God in their own image and likeness.
God as immaterial and yet with biological functions is unconvincing
It’s self-contradictory to say God is ‘immaterial’ and in the same breath say God sees, hears, speaks, and feels—all of which are functions of biological, material organisms. What does God ‘see’ with if not a material eye? ‘Hear’ with if not a material ear? ‘Speak’ with without a material mouth? These descriptions of God are self-contradictory and nonsensical.
God as all-knowing is unconvincing
Does God know terror, fear, pain, indigestion, menstruation, sexual attraction, sexual climax, pregnancy? Does God know the last number? No one is all knowing. Again, a nonsensical claim.”
God as all-good is unconvincing
God is all-good and yet made a world that is bloody red in tooth and claw? God is all good and made predators and prey? (A lion might love the arrangement, but the hapless gazelle and bunny rabbit do not.) God is all-good but made the talon and the fang? God is all good but made 50,000 pathogens that are trying to kill us and the animals? God is all good and made diseases? What about all the suffering of animals and humans? In human affairs, would we call a person ‘good’ who sits by as a six year old boy beats a two year old girl and her pet kitten to death? No, any good person would intervene. And yet God has allowed a near infinity of pain and suffering to exist. Either God is not all good (or not all powerful) or God does not exist: these are the only explanations for the high degree of animal and human suffering on earth. More likely, there’s no God.
