Elroch - if the earth was known to be some ball floating around in a vacuum of space for 1000's of years, then why did it take the Catholic church the Catholic Priest Copernicus and the Jesuits to propagandize it across the face of the earth? And even then, it required Newton some 200 years later to create a math to support the idea that people are walking upside down in the southern hemisphere with respect to those in the northern hemisphere.
I suppose one must assume every single person on earth(with a few exceptions) was just dumb until 1492.

The moon could be spherical.
It is.
It certainly has the appearance of being so.
Indeed.
But is it a rotating sunlight reflecting rock ball?
Everything reflects sunlight to some extent. Proving it is not made of cheese is not so simple, I'll accept.
Observably not.
No. Glib claim that can't be backed up.
Does it cause the tides? Demonstrably not.
Another glib claim
Note that both the sun lighting the Moon and the Moon being the main cause of tides are strongly supported by the evidence. The phase of the Moon is determined by where the Sun is in the sky. When it is opposite the Moon, the Moon is full. When it is roughly the same direction as the Moon, the Moon is new. Other angles give the expected phases.
Likewise the tides are confirmed to be caused by the Moon because they are closely related to where the Moon is in the sky. Rather than being at the same time of day, they are at the same location of the Moon in the sky as the Earth rotates.
(The exact relationship depends on location, because water takes time to flow, and the time varies with location, but the relationship is a very regular one for a given location, only perturbed by the secondary effect of the Sun, which causes weaker tides).
The role of the Sun is made clear by the fact that the strongest tides ("Spring tides") are when the Sun and Moon line up and the weakest tides ("Neap tides") are when they are near to right angles from each other. There are thus two Spring tides and two Neap Tides each lunar month.
