Theological non-cognitivism is the claim that statements like, "God exists," "God is good," and "God loves me," are not only false, but literally meaningless. It amazes me that even a small segment of the atheist population still adopts this view. Although some significant work had been done prior, it was likely Alvin Plantinga's The Nature of Necessity that put the final dagger in theological non-cognitivism, logical positivism, and the verification principle.
I say that theological non-cognitivism (TNC) is the atheist's equivalent to the Christian's Young Earth Creationism (YEC) because there is a trend among both groups to ignore either scientifically or philosophically compelling reasons to reject them. Science clearly shows the universe has existed for roughly 15 billion years.
Moreover, the creation account in Genesis 1 has for centuries, and now millennia, been interpreted figuratively. I won't go into great detail here, but you'll see how Days 1 and 4, 2 and 5, and 3 and 6 each correspond to one another. On Day 1, God created light, whereas on Day 4 God created the sun and the moon. On Day 2, God separated the land from the sea, and on Day 5 God created sea animals and birds. Finally, on Day 3, God created land vegetation, and on Day 6 God created land animals of all sorts, including human beings. In other words, the author of Genesis was simply using a rhetorical device in order to illustrate the hierarchy of creation.
The problems with TNC are many as well. When a theist talks about a Cosmic Designer who transcends the universe, and is therefore timeless, changeless, immaterial, eternal, indestructible, and enormously powerful and intelligent, what's the objection the proponent of TNC has to offer? There can be no immaterial mind, and the very concept of an immaterial mind is incoherent, as I often hear from these TNC proponents? If that's all they have to offer, then they're simply begging the question against theism. On what grounds does the TNC-er make such an unsubstantiated claim?
