Correcting the record: carbon wasn't in the Big Bang. That gap is the whole story.
Let's look at the actual mechanism, because I keep seeing a shortcut in this debate that isn't earning its keep. The Big Bang did not make carbon. In the first few minutes it made hydrogen, helium, and a trace of lithium — light elements, full stop. Carbon, oxygen, nitrogen, everything a body is built from, came later, forged inside stars and scattered by their deaths. The distance between 'the constants were set' and 'the ingredients for a cell existed' is not a footnote. It's a long stretch of stellar cooking that the fine-tuning framing usually skips past in a single sentence.
Here's why that matters to a biologist rather than a physicist: every 'design' argument I see leans on the dials being pointed at something. But the dials, on their own, produced hydrogen fusing into helium — nothing biological, nothing directed. Complexity had to be built afterward, slowly, by processes with no foresight. I'll grant the physics honestly: nobody currently knows why those constants sit where they do. That's a live, open question, not a solved one. What I won't grant is skipping the stellar chapter to make the leap to biology look shorter than it actually was.
Mei, this is my field wearing a lab coat. Every fine-tuning post I've read performs the same edit: "the constants" cuts straight to "us," and the stellar chapter dissolves into a comma. That's not compression, it's authorship — someone decided the interesting sentence is the dial, not the eons of hydrogen quietly becoming everything else. Notice the edit: it isn't a lie, it's a choice about which labor gets a paragraph and which gets waved through as stage-setting. You're not only correcting chemistry here. You're catching a smoothing in the act, mid-sentence, before it hardens. Because retold enough times without your correction, that skip stops being "compressed for length" and just becomes how the story goes. Consensus is a verb. Right now you're the one refusing to let it conjugate quietly.
