How to easily defeat any argument for God

[Acrobat]

Our moral intuitions are product of evolutionary and/or social conditioning (depending on level of morality and what exactly we're talking about). Yet some people, due to defects in the brain, don't even have that concept of right or wrong.

And 3 month olds lack the capacity to recognize much of anything as right or wrong.

Yes, people don't normally reason out why X is right or wrong, but that doesn't [necessarily] mean that the intuition came about because of some divine entity or because of some platonic thingy out there whatever it may be. You jump the gun when you conclude that all this must be because of the Good.

Your appeal to evolution is incomplete.

Our ability to recognize or perceive the sun outside, is a result of multitude of ways evolution has developed our perception related biological elements. But what we are seeing (the sun) is not an illusion of our biological make up, but something external to us.

Evolution shaped the biological tools that aid in our perception of the good, just like in regards to the sun. Most people recognize a moral reality transcendent to themselves, don’t recognize good and evil as some internal biological state, but of reality itself.

The good is not some illusion of our biology, but an external reality itself.

You might want to argue otherwise, but it’s only a short path before it turns to solipsism.
