The Fine-Tuning Argument (FTA) is one of those standard arguments for the existence of God. The argument goes that humans can only arise when the parameters of the universe are tuned exactly right. And while it’s possible that we just got lucky, the argument goes that it’s far more likely that God did the tuning.
The standard way to talk about the FTA is delve into a bunch of math equations. Not that there’s anything wrong with math, but here I wanted to write an in-depth overview that doesn’t talk about the math. There will, however, be a lot of physics. The goal here is not to refute the FTA (although refutations will occur incidentally), but to explore it, and to understand how we test hypotheses about the universe.

The parameters of the universe
The core premise of the FTA is that the universe is fine-tuned. Which is to say, the probability of life looks like this:
