You tried. Some things just can not be accepted by people. The light house picture from across lake michigan, can be explained several ways by both sides, so that is pretty much a wash, if it is provable the image was not altered, then the most plausible reason is that there was a temperature inversion, ow which I am sure being in the north you are quite familiar with the city in the sky mirages due to temperature inversions.

The north and south poles and and stars not moving or changing, why do people see different stars in the southern hemisphere if the earth is flat, and the stars do move in the sky it is just a long term prospect.

But the one thing none of the flat earthers have ever been able to answer is how did the continents come to be where they are?

I applaud your effort.
