10. Wikipedia.

Entropy is related to the number of ways a certain situation can be realized. The more microscopic ways there are to create the same macroscopic situation, the higher the entropy of this macroscopic situation.

I believe, you forget that though atoms are not unique, they are treated as unique individuals in this context.

Let's say, we have a crystal consisting of 4 metal-atoms. There are 4!=24 ways to build that crystal. If we have a crystal of 2 Na and 2 Cl-atoms, there are 2!*2!=4 ways to build that crystal.

Let's say we compare an ice-crystal and a water-droplet. The ice-crystal is an ice-crystal only if the water-molecules are at the right locations. The water-droplet is still a water-droplet if the water-molecules are slgihtly out of position.
There are more ways to make a water-droplet than to make an ice-crystal.
Liquid water has more entropy than ice.

Let's say we have a non-living matter and living matter. The non-living matter stays non-living matter if a few atoms are slightly out of place. The living matter dies if too many atoms are out of place.
There are less ways to make living matter than there are to make non-living matter.
Living matter has less entropy than non-living matter.
