What happens when a frontier AI system is given one hard question and allowed to investigate it in the open?

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. The model 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.

What the book contains

The report finds no proof in either direction. Its calculated probability is presented with its assumptions exposed, including how far the answer moved during review and how widely coherent skeptical and theistic positions diverge.

How to read it

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 The work has not been peer reviewed. It is offered as a transparent record for readers to examine, not as a verdict on faith.

Formats and availability

Buy it directly from Full Circle Storyworks for US$7: the EPUB, the PDF reference edition and three companion reports showing how other AI systems answered the same question. The companion reports are only available here. All files are DRM-free. The book alone (EPUB and PDF) is also on Gumroad for US$5, and Kindle, Apple Books, Google Play Books and Kobo editions are in each store's review.
