The big idea: The last micro asked whether words about God can be accurate. This one asks something harsher: whether they mean anything at all.
A rule for meaning: In the 1930s a group of philosophers proposed a single rule for meaning. If you took it seriously, whole sentences about God didn't come out false. They came out empty, like a light switched off.
The rule is called verificationism. It's the most famous modern challenge to religious language, and you meet it through one clear voice.

The British philosopher who put it most sharply set out a simple test for any statement.
Ayer's verification test: A.J. Ayer argued that a statement is only meaningful if it is one of two kinds.
The two kinds of meaningful statement
- True by definition — like 'all bachelors are unmarried'. You see it's true just by understanding the words.
- Checkable by experience — like 'it's raining outside'. You know what would show it true or false: you look.
Now test 'God exists': Anything that is neither, Ayer said, is not false — it is meaningless. Now test 'God exists'. It isn't true just by definition, and no experience could confirm or rule it out. So by the rule it says nothing at all.
Checkpoint — Ayer: In one line: if no possible experience could check it, Ayer says it isn't false — it's meaningless. Hold that — the next step is why this landed so hard on religion.

Notice how different Ayer's attack is from an ordinary disagreement about God.
Not 'you're wrong' — 'you're saying nothing': An atheist who argues 'God does not exist' is still treating 'God exists' as a real claim — one they think is false. You can argue back.
Ayer's stranger move
Ayer's move is stranger and, for a believer, harder. He doesn't say 'God exists' is false. He says it never rose to the level of true or false — it's on a par with 'the number seven is jealous'. There's nothing to argue about, because nothing was claimed.
Why it unsettled believers: That's why the challenge unsettled religious thinkers: you can defend a claim, but how do you defend a sentence that's been declared not a claim at all?
Go further — higher-level insight: There's a famous sting in the tail: apply the verification rule to ITSELF. 'A statement is meaningful only if checkable by experience' — is that itself true by definition, or checkable by experience?
The self-undercut: It seems to be neither, so by its own rule it would be meaningless. This self-undercut is the single most powerful reply to verificationism — keep it ready for a top-band paragraph.
Checkpoint — the challenge: In one line: verificationism doesn't call God-talk false — it calls it empty, which is harder to answer. The next micro gathers the serious replies believers give.
