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.

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.

NameofNames - the main premise of heliocentrism is a ball earth with an uncontained atmosphere(air pressure) coexisting aside an uncontained vacuum. Ever see what happens when a contained vacuum is subjected to air pressure? It implodes. 

That is why the ancient astronomers referred to planets as 'wandering stars' each having their own distinct patterns. But they never referred to them as terra firma. 

That would be foolish because "terra" means Earth. The ancient astronomers knew less than modern astronomers. Not sure if you have heard by they had no telescopes or computers.
Breaking news - they were not good at video games either.

One can see sky through the moon, therefore it is observably semi-translucent. 

If the moon causes the tides, then why does it not affect ALL bodies of water?

Elroch - well, they mapped out the constellations and made accurate cosmological predictions. 

But they did not claim to observe stars light years away or some perfectly synchronized with earth rotating sunlight reflecting moon so only the same side is visible to everyone on earth forevermore.

Yes, they knew some things. They were smarter than your guy who doesn't understand rotation (geometry was an ancient strength - Euclid and all). As well as mapping the stars and identifying (if not understanding) the visible planets, they worked out the Earth is ball-shaped.

Telescopes help a lot. Here is a sequence of photos of the Moon made into a video.

Heliocentrism is full of stuff that requires a "leap-of-faith"! 

The heliocentric moon being one.

I posted for you part of that interview the scientist from the 60's that claimed the moon was made of Plasma.

Who cares?

He presumably had some sort of mental illness: anyone can tell the Moon is at least primarily solid, since its features have been stable for hundreds of years.  Plasma has no rigidity, so, features made of it would change over time, like those on the Sun's surface. (The features of the atmosphere of Jupiter also change over time because it is fluid).

The Earth is an oblate spheroid with a slight bulge just South of the equator which actually gives it an egg shape. There is a 'flattening of the Poles' which occurs because of the rotation. The Universe is flat, not the Earth. You guys should argue the number of dimensions in the universe. There are 13. Or whether time is a dimension. Or whether a singularity can exist. Or the shape of the universe. There are more questions in Astronomy and Quantum Mechanics than there are answers. Is the universe infinite or finite? Do you grow discreetly or analogously? Can you snort chocolate and see God? Don't try this at home, Kids, it doesn't work. 😁🙄😥🤣

No, you can't. The sky is light from the atmosphere, just a few miles above you, and the Moon is way BEHIND that. The Moon can be seen THROUGH the blue of atmospheric scattering because it is bright enough.

If the moon causes the tides, then why does it not affect ALL bodies of water?

It does, but the size of a tide is related to how far the water extends. A lake is all at almost the same distance from the Moon, so the tides are small or insignificant. 

The world's largest lake - the Caspian Sea - has tides of up to 5.4 centimeters.

Mediterranean tides are also small because although it isn't a lake, there is only a small channel to the Atlantic past Gibraltar.

This answers your question.

It is useless to argue with the air.

Can anyone prove the moon is a rotating sunlight reflecting rock ball i.e. rotating in perfect sync with a rotating spherical earth so only one side of the moon is visible?

Can anyone prove the sun is 400 times larger than the moon and 93 million miles from earth?

If not, then they are simply beliefs. 

If there are indeed 1000's of satellites orbiting earth, then why doesn't NASA simply show the moon rotating 24/7? 

Heck, they claim to have a camera pointed at earth from the ISS with a 24/7 live feed.

Satellites aren't that much closer to the moon than we are when standing on the surface of earth... they're also mostly pointed at the earth e.g. communication satellites... I can only assume the vast majority aren't cameras and also aren't owned by NASA.

aoidaiki - That would be a reason but not a good one. However, they do claim to have satellites that can zoom right in on the earth and view people, places and things. 

Most communications between continents are done through fiber optic cables that crisscross the oceans. They are still laying these cables to this day. 

NASA is also the largest consumer of helium in the world, and they have been launching helium balloon satellites since the 60's.

Pretty sure that's not possible due to the atmosphere not being completely transparent. You're looking down through a lot of dust and water.

Trump accidentally leaked the fact we have satellites that can do a lot better than people thought, but nothing that can zoom in and identify a person.

I don't know about identifying an individual but they do claim to be able to view people etc. If they are using their helium balloon satellites which hover in the stratosphere then it certainly is more than possible it is probable.

Bro, there are videos of rocket launches dating back at least 70 years... you're awfully stuck on helium.
