It is pretty clearly spherical, if you pay attention.

>* Speaking of the Moon, is it not remarkable that the only face it discovers to us is *flat* while the one no one ever saw is rotund?

Pic related, you are retarded.

PS: I am sorry that you are retarded.

>Apparently we only see one side of the moon

We see a bit more than half the moon's surface, since the orbit is elliptical, it speeds up and slows down in its path around the Earth while it spins at a constant rate, so pic related happens.

Earthlight (reflected light from Earth) will always shine on the side of the moon facing the Earth. it will be a lot of light when the Earth is full, as seen from the moon, and a lot less as the Earth goes further and further into crescent and then "new" phase. Even when the Earth's shadowed side is totally facing the moon, you'll get a little light through the atmosphere, and a very VERY small amount from things like city lights.

Earthlight, at its brightest, will be brighter than moonlight as seen from Earth.

But sunlight is a LOT brighter than that, of course. As we see the moon run through its phases in a month, we see the sunlight illumination moving around the globe of the moon.

A little more than half of the lunar surface will see some Earthlight at some point (The moon "wiggles" a little bit as seen from Earth since it's orbit is, as orbits are, elliptical, meaning the moon's speed in orbit varies more during a month than its speed of rotation. A btit less than half of the lunar surface never sees any Earthlight, and is never visible from Earth.

But all of the points on the lunar surface see the sunlight over the course of a month

but that's wrong

Here's a pretty good illustration of the moon being spherical. As months go by, and it moves from apogee to perigee, the moon "wobbles" a bit in its orientation with Earth, and we can see a bit more than half of it over time.

Here's an interesting gif made of pictures of successive full moons...
