No way can you all be missing the point. Not a chance.
We get the point.
You made a blatantly false claim, which is trivial to show is wrong, and now are trying to hide from it.
It all started because you wanted to claim the moon should be super super bright, even though evidence shows otherwise.
It only easy to be fooled into thinking it is massively bright during a full moon, when you have the moon quite well illuminated by the sun (like daytime on Earth), and it is the brightest thing in the dark night sky. With that, and your eyes adjusting for the darkness, it appears quite bright. Unlike say a half moon which is also visible during the day, when your eyes are adjusted for seeing the daylit Earth, and the moon almost blends in to the sky due to just how dull it is.
This particular tangent all started with you claiming:
People on Earth see a full moon all of the time.
The phases are only related to where a person is stood when the moonlight is obscured from their position, after full moon.
A factually incorrect statement, trivial to disprove and a vague one where you don't make it clear if it is related to their position relative to the moon (reality, where everyone sees the same phase at a particular time, assuming they could see the moon), or relative to Earth (fantasy, where different people seeing the moon at the same time see a different phase)
You then changed it to a factually correct but vague statement of:
At some stage all people see a full moon somewhere on Earth.
This could mean over time people will see a full moon, as at some point in time, there will be a full moon and everyone can see it.
Or, it could mean that over time, the full moon will be visible to a different region of Earth as the phases change based upon position.
You really should have just left it at that vague statement.
But you couldn't help yourself. That was because someone called what you claimed nonsense and you responded with this:
I know you're only joking around. If I'm looking at a waning moon tonight, then everyone everywhere else in the world is also seeing a waning moon.
Absolutely not.
Which while technically correct, as Earth gets in the way for some people resulting in them not seeing the moon at all, and other people would be inside unable to see and so on, but the point conveyed was that these other people would see a different phase.
This was clarified:
Sceptimatic, do you imagine that two people looking at the holographic moon projection at the same time from two different parts of the world can see different phases of the moon?
Could I see a half moon and someone else be seeing a full moon?
Absolutely if you're on different parts of the Earth.
Where you agree that the phases of the moon depend on where on Earth you are standing.
So it is quite clear what you are claiming.
That the phase of the moon varies with location on Earth. That 2 people in different locations on Earth, both with a clear view of the moon, can be seeing fundamentally different phases, where for example, one person sees a full moon while another sees a half moon.
You even further emphasise this with this claim of yours:
Every person sees a full moon somewhere on Earth, at all times.
If I see a full moon then the full moon moves away from me, someone else sees a full moon.
Someone is always seeing a full moon.
Again, this is factually incorrect.
Currently the phase of the moon is a waning Crescent.
Just where on Earth can anyone see a full moon?
Here is a rare photo of a full moon from when everyone on Earth had a new moon:
https://epic.gsfc.nasa.gov/epic-galleries/2015/lunar_transit/full/197_2015197222104.png(due to the way in which the picture is taken, taking the separate colour images in sequence, there is significant chromatic distortions, with the moon moving while the picture was being taken)
This is also a strange full moon as it shows the far side of the moon, rather than the near side we are all familiar with.
And because the camera is adjusted for taking images of Earth brightly lit up by the sun, the moon doesn't really appear bright at all.
But if you are on Earth, EVERYONE who can see the moon, sees the same phase at the same time.
