It's good, confirmation bias.
As ever the FE beliefs in this are are a mass of contradictions.
It's claimed that we know the earth is flat because ships don't really sink below the horizon, they can be "restored" with magnification.
Except when magnification clearly shows a ship or building sunken behind the horizon in which case it's waves, or perspective.
FE always wants to have its cake and eat it, there are lots of "heads we win, tails you lose" arguments and this is one.
Ships don't really sink below the horizon, they can be restored with optical zoom is one claim.
Now, sometimes a speck out at sea can be hard to see clearly, and maybe a dark hull may be harder to distinguish from the sea than a light top of the ship.
In that case yes, optical zoom will "restore" the ship but I used the word advisedly, all it will do is make things clearer. So now you can distinguish the dark hull from the sea. But it hasn't magically made anything appear from behind the horizon which was previously occluded, it was never behind the horizon in the first place.
But if the ship is going away from you then it will sink below the horizon just like the sun will always set.
Yes, there may be atmospheric effects which mean this doesn't happen exactly as a model with a perfect sphere and no atmosphere predicts, atmospheric effects can be complicated.
But the ship does always sink, the sun does always set. That is the consistent thing and one of the things which proves we live on a globe.
You don't get a ship going further and further away and you can keep on restoring it with optical zoom, it always sinks behind the horizon, not behind imaginary perspective lines which are a feature of art, not physics.
