This ultimately gets into a concept called the Anthropic Principle. In a nutshell, if things were any different, we wouldn’t be here in the same way.
For instance, let’s assume for a moment that there is no God. Let’s also assume something like a multiverse.
Okay, now how do we get something like humans? Well, we need a universe that allows for humans to arise in the first place. There are going to be many universes in the multiverse, all with different laws and compositions. Some universes won’t even have atoms, but other constructs entirely.
But let’s say we look at the universes that contain atoms – entities that move around and follow laws. In one subset of these universes, maybe the strong nuclear force isn’t strong enough and nuclei never form. Humans, therefore, never come to exist in that universe.
Let’s look at another – maybe one where vacuum energy is really high. Galaxies would never form.
You can look at all sorts of different universes and notice that they all have different tweaks of parameters, different structures, different laws, etc. But only a few of them are going to ultimately yield sentient life – the universes where the forces are just right to allow for galaxy, star, and planet formation (or any other structural formations that are conducive to sentience). One where conditions, in that subset, are diverse enough to allow for abiogenesis/natural selection to take place. And, eventually, we have something resembling intelligent humans.
In the paraphrased words of Douglas Adams, it isn’t really surprising to notice that if you’re a puddle of water, the hole you’re in fits you perfectly. Don’t think of human sentience as anything special. If conditions were different, you wouldn’t even be alive to know it. The only way a human can even KNOW it’s human is if it’s ABLE to physically know, and to physically know, you have to be in a universe that ultimately allows for those conditions to come about. Odds are, universes that allow for conscious sentience have some sort of mechanism involving Darwinian natural selection (simplicity to complexity).
Meh just some food for thought.
