Explain how materialism and morality are incompatible
If materialism is true, then everything...including us...is just "materials." That means we are entirely contingent entities, drifting without objective purpose through a universe completely indifferent to us.
And we're animals. As animals, we have no moral duties. Lions are not "evil" for killing zebras or each other (they do both, actually). We're not even "evil" if we strip the planet of all life. For who's around to say, "You shouldn't do that"? Genocides? Not evil: just another way people can choose to behave. Rape? Just fine, if you can get away with it. Murder? No such thing, really...just another contingent choice for purposeless creatures.
Nietzsche saw all this. And he was brave enough to say it. But the Atheists who have come after him have mostly not had his courage.
Explain how if morality is not a mental concept where it comes from
According to Materialism, there are no "mental" phenomena. We might think there are, but they are just another arrangement of "materials": the brain playing tricks called "mind." They have no objective reality.
So when you say, "I don't like murder," that's just because the molecules in your skull happened to line up that way. And when Stalin says, "Well, I do!" then that's also because of the arrangement of molecules in his skull -- no more. And neither one is more "moral" than the other, because "moral" refers to nothing but a delusion.
