Well, just looking at the first one there is quite obvious evidence of curvature.
We can see the horizon curve back and forth as it moves up and down. Entirely consistent with a fish-eye lens.
The horizon is below the centre, and thus the curvature of Earth is cancelled by the distortion induced by the fish-eye lens.
So I won't bother with the other videos.
As for the text:
The stars rotation prooves Flat Earth, because North star is always on the Dome in its centre and the North Star doesnt move. and all other stars rotates around it in PERFECT CIRCLES that only God Almighty could have made.
You mean that the rotation of Earth perfectly explains?
No need for any magic god.
But this is a massive problem for the FE.
Why do they appear to trace circles?
If Earth was flat and these stars were close by, then they would only trace circles for those along the axis of rotation. For anyone else, looking so far off axis, they would appear to trace ellipses instead.
If the stars were far away, as needed to make them appear as circles to everywhere, then they sky would appear the same to everyone.
And that brings us to another big issue, why are only some stars visible from some locations? Why can't everyone on Earth see the same stars?
And the final nail down that path is that it isn't only in the north that that happens.
In the south, we also have stars trace circles, but around the south celestial pole.
And the south celestial pole is always 180 degrees away from the south celestial pole, and you can circle both.
This is impossible on a flat Earth as it requires 2 straight lines to intersect twice with some finite distance between the points of intersection, which is simply impossible.
Bible prooves Flat Earth
Not how it works. If a book claims the Earth is flat, that does not prove Earth is flat.
Instead the fact that Earth is round disproves the book.
