The Copernican Principle is looking weaker than ever. Almost every solar system we find has similarly-sized planets, or planets ordered in an unfortunate way, or shitty suns that bleach them every two weeks. We continue to find system after system after system which looks absolutely nothing like ours.

And there's lots of evidence that we've hit a million unlikely goalposts. We might've gone through more than one great filter already. Whether it's going multicellular, or having a protecting planet like Jupiter, or having Theia slam into us and giving us a moon for tides, or any number of other weird things.

And that's before getting into our specific evolutionary past. If it weren't for dinosaurs ruling the planet, we might not, as mammals, have evolved our extreme adaptability. If it weren't for them then getting wiped out, we wouldn't have had a planet-sized sandbox where nearly every niche was suddenly open again, allowing us to explode in complexity as we essentially spent all day solving survival puzzles. Even then, all of this could've happened underwater and it wouldn't have mattered, because we never would've made fire.
