I think that’s not actually Pangea (the past supercontinent), but a rendition of Pangea Proxima (the future supercontinent). So just gotta wait a while…

We aren’t at that spot, but in space above and behind it. Our horizon is different to the horizon at the prism, and on the surface there the Earth may well be slightly below the local horizon. Hard to say for certain since this is AI slop and the perspective may be wonky.

That being said, the prism is so tall that it would probably still be at least slightly visible from the Earth.

Only if you take it literally. Oftentimes people call the far side the dark side (dark as in unseen).

Although the far side does get a lot darker than the near side during lunar nights, since Earthshine never reaches it.

I think the point is that they aren’t assuming the planet in question is tectonically activie, as that’s one of the unlikely steps needed for life as we know it.
