Only here: the direct edition includes three companion reports showing how other AI systems (OpenAI GPT-6 Astra, Anthropic Claude Fable 5.1 and Google Gemini 3.1 Pro with Deep Research) answered the same question. They are not sold anywhere else.

What you get for $7.00

One question. Four AI answers.

The book is one frontier AI system's complete investigation of whether the Christian God exists. The direct edition adds three other AI systems' answers to the same question, so you can see how differently machines reason about it.

Three rival AIs. Three different answers.

Each companion report is the system's own unedited answer, with a title page naming the model. Compare their reasoning, and their numbers, with the book's.

  1. OpenAI GPT-6 Astra · Ultra

    ≈ 20%

    its probability estimate (5–60% span)

    Weighs the arguments from existence, design, morality and the resurrection against suffering and divine hiddenness, then shows its arithmetic.

  2. Anthropic Claude Fable 5.1

    ≈ 10%

    its central estimate (3–25% range)

    A brisk map of both cases that ends in a calculation table contrasting apologist, agnostic and naturalist starting points.

  3. Google Gemini 3.1 Pro · Deep Research

    0–100%

    its verdict: it all depends on your prior

    Builds the cumulative case for God, then declines to name a number: the answer, it says, depends entirely on where you start.

About this book

On 22 September 2026, a frontier AI model was asked to do a deep dive on proving the existence of the Christian God, and then to calculate a probability range. It organised its own multi-agent research programme: researchers for thirteen clusters of arguments, auditors from both theist and naturalist standpoints, a completeness critic, a Bayesian modeler, independent reviewers, opposing challengers and a final adjudicator. This book preserves the complete result as a dated research record: 99 arguments for and against, the evidence ledger, the Bayesian model with Monte Carlo simulations and sensitivity analysis, all 60 rulings, and about 680 sources. The report finds no proof in either direction.

AI disclosure

The research text is AI-generated and is reproduced without alteration. The AI system used is identified inside the book, and the publication is independent of its provider. Formatting, links and navigation were prepared for publication, and problems found by later source verification are marked in clearly labelled editorial notes. The work has not been peer reviewed. The companion reports are other AI systems' unedited answers to the same question and have not been fact-checked.
