Here's why:
* Monolith = One Stone: The word "monolith" itself implies a single, massive piece of rock.
* Structure vs. Composition: A monolith is a geological formation or a structure made from one solid piece of rock, not an assembly of smaller stones.
Think of famous monoliths like:
* Stonehenge: While Stonehenge is a complex structure, its individual standing stones are considered monoliths.
* Easter Island Statues: These are monoliths carved from a single volcanic rock.
So, while you can count individual stones in a structure like Stonehenge, you wouldn't talk about counting stones in a monolith itself.
