The God question
The Strongest Arguments Against God
Not proof. A weight of evidence, presented the way careful philosophers present it.
Nobody can prove God does not exist, and serious philosophers on both sides know it. What the arguments below establish is that theism is a less probable explanation of the world than naturalism, not an impossible one. Leading that way makes everything after it more credible.
1. The evidential problem of evil
William Rowe's case: a fawn is trapped in a lightning-caused forest fire, horribly burned, and dies over several days, unseen. No free will involved, no one to learn from it, no one watching. Multiply by roughly 500 million years of animal suffering before humans existed. SEP
They will say: we cannot judge God's reasons, like a beginner judging a grandmaster's move. A respected position, with a steep cost: if our judgment is too weak to identify pointless suffering, it is equally too weak to identify God's goodness, so it undercuts every positive claim about God too. And a loving parent, unlike a competitive grandmaster, has every reason to explain rather than hide why a child must suffer.
2. Divine hiddenness
J.L. Schellenberg: a perfectly loving God would ensure that anyone open to relationship could believe he exists, because you cannot have a relationship with someone you do not think is there. Nonresistant nonbelievers, sincere seekers who are not convinced, plainly exist. SEP
This is harder to answer than evil, because it cannot be blamed on human sin. By definition these are people not resisting.
They will say: hiddenness protects free will; forced belief is not real love. But those goods do not require nonbelief. You believe your parents exist and still freely choose the relationship. Belief and free love are not in tension, so hiddenness buys nothing.
3. Belief tracks birthplace
Conviction follows the map
Religions make mutually exclusive claims, but belief clusters by geography, not by evidence.

A child born in Riyadh becomes Muslim; in Salt Lake City, a Latter-day Saint; in Rome, Catholic. This is the most conversationally effective argument on this page, because it is checkable and needs no philosophy.
4. Naturalism’s unbroken track record
Every phenomenon once attributed to direct divine action, disease, weather, lightning, mental illness, planetary motion, the origin of species, has, when actually investigated, turned out to have a natural explanation. The pattern runs one direction only. No gap has ever been closed by confirming a supernatural cause. SEP
Be honest: this is inductive, not deductive. It cannot rule out that consciousness or cosmic origins is the exception. But believers have staked God on specific gaps repeatedly, Newton on planetary orbits, pre-Darwinian biology, disease as demonic, and lost every time a gap actually closed.
5. Burden of proof, as framing only
Russell's teapot: nobody could disprove a china teapot orbiting between Earth and Mars, and that is exactly why the burden falls on the person asserting it. Hitchens's razor: "What can be asserted without evidence can also be dismissed without evidence."
Believers correctly point out that the teapot framing assumes there is no evidence, which is the thing in dispute. It sets the table; it settles nothing alone. The same goes for omnipotence paradoxes like the stone God cannot lift: theists resolve those by defining omnipotence as the power to do anything logically possible, which is a legitimate move. Build nothing on either.
Why this should make you question
Taken one at a time, each of these has a reply a thoughtful believer can give. Taken together, they describe a world that looks exactly like one with no one home: suffering distributed without regard to merit, a God undetectable to sincere seekers, belief predicted by a map rather than by evidence, and every mystery ever solved, solved naturally. That is not proof. It is a lot of evidence pointing one direction.
