Will science and technology eventually make religion obsolete? Physicists Paul Heslop and Simon Walker-Samuel join host Sam McKee for a fascinating clash of worldviews on the future of faith.

This debate took place in front of a group of teenage students from Sir Henry Floyd Grammar School in Aylesbury, UK, in partnership with Aylesbury Vale Youth for Christ.

As artificial intelligence, genetic engineering, neuroscience and space exploration transform what it means to be human, will people still believe in God by 2100? Christian mathematical physicist Paul Heslop argues that science cannot answer the deepest questions of truth, meaning and existence. Humanist biophysicist Simon Walker-Samuel asks whether religion is instead a human response that advancing science may increasingly leave behind.
From AI consciousness and free will to morality, evolution and the search for God, this Unbelievable debate asks whether our technological future will finally displace religion, or reveal why we still need it.
