Sunday OT:

One day (during latest partial solar eclipse) I suddenly realized that the fact that Moon exactly blots out the sun is somewhat weird and is highly unlikely.
We just happen to live at the time when angular diameter of both the moon and the Sun are virtually identical.

Although it is exactly what is happening, the even itself has microscopic probability from all possible arrangements between the size of the planet satellites, the star, distances, etc, etc.
That made me think about other "unique" features of the realm about "right now":

1. First off, all universe parameters had to be just right to make stable atoms, galaxies, etc-that's a given. Our Universe is just one out of roughly 10^500 chances. Good enough!
2. Sun had to be formed after heavy elements already accumulated...almost 8 bil years after the Big bang...basically, we are 'late".
3. Humans appear on earth 4.7 bil years after the planet was born and the planet has a maximum of another 1 bil years to go before the biosphere is is bound to be destroyed by the expanding Sun that would be transitioning to a red giant. So, we appeared within the last 20% of the planet's life.."late" again.
4. The Moon is larger that the satellite of the earth size planet should be theoretically with astronomers proposing (and basically proving) that the Moon was formed by the collision of the "initial" earth with a body the size of mars, roughly.
5. That collision probably evaporated the original water on the planet and resulted in Earth being drier that it would have been otherwise, with most water being brought by comets and asteroids.
6. It is entirely possible that the core rotation and magnetic field plus tectonic plates movement was also caused by that collision, which ought to be a very rare event.
7. We are here during the time when we can still see galaxies. Some time later...in fact, much later, other galaxies will be invisible to us.
8. We live at the age when computing became widespread. Being born a hundred years early and we would have missed it.
9. Being born as "you"-that's a biggie. Each human mating pair is capable of generating at least several dozen trillions genetic combinations, but here you are. Chances of winning a lottery are at least 100 thou times larger than that. Add to that you personal unique history that added to you being you.
9. We live during the age of bitcoin "discovery", so we could participate early, which is almost like having a golden ticket and/or winning a lottery (again).

TL;DR Sometimes I wonder about all this 'selection' mechanisms that resulted in "now", but then, it all depends on the number of "rolls".
