"And in yourselves — do you not see?" — Quran 51:21. Your eye contains 130 million photoreceptors. Every cell in your body carries 3 billion chemical letters of genetic code. Your immune system recognises millions of threats it has never encountered before. In this episode, we follow the Quran's direct instruction to look inward — at the architecture of the human eye, the language of DNA, and the extraordinary coordination of organs — and ask what this level of specified complexity implies about its Designer.
