What could be logically weaker than the theory that God is a projection of human needs? Supposedly God does not exist because his existence reflects human exigencies. This argument presupposes that God could exist only if man did not need Him. What could be more absurd? But then, why is this idea so widespread?

The Continental philosopher will often say in an obscure and confusing way what the analytic philosopher can say clearly. Allow me to demonstrate.
God cannot be a human projection. This follows directly from what we mean by 'God' and what we mean by 'projection.' By 'God' we mean a being whose existence does not depend on the existence of anything else. That is not all we mean by 'God,' but it is an essential part of what we mean. So if God exists, he exists in splendid independence of humans and their wants and needs. By 'projection' we mean either a projecting or that which is projected in a projecting. (‘Projection’ is an example of process-product ambiguity.) Either way a projection cannot exist without a projector. It follows that God cannot be a human projection. We know this by sheer analysis of the terms 'God' and 'projection.' For nothing that is a projection could satisfy the concept God. Again: if God exists, then he exists independently of anything else that exists. The Latin word for this divine attribute is aseitas. In plain Anglo-Saxon, ‘aseity’ means in-itself-ness.
Does it follow from the divine aseity that God exists? No. But that is not the point. The point is that God cannot be a human projection, pace Ludwig Feuerbach (1804-1872) and his followers. God obviously cannot be a human projection if he exists. Suppose God does not exist. Then there is nothing in reality to which the term 'God' applies. The nonexistence of God leaves both the meaning of 'God' and the concept God intact. So it is not the case that if God does not exist then the concept God becomes the concept of a human projection. That’s the salient point. The concept God remains the concept of something such that, if it existed, it would not be dependent on anything else for its existence, and therefore, the concept of something such that, if it existed, it could not be a human projection.
So what is Ludwig Feuerbach's signature sentence, "God is an unconscious anthropomorphic projection," about? Despite its surface grammar, the sentence cannot, given the cogency of the above reasoning, be about God, but about our concept God. What it says about this concept is that nothing satisfies it. But then Feuerbach begs the question against the theist.
Del Noce asks, “But then, why is this idea so widespread?” Because people are either incapable of thinking clearly, or unwilling, or both. Why would people be unwilling? Because it takes concentrated effort, and people are inherently lazy, even your humble correspondent, and made even lazier by a decadent society and a corrupt government.
