Is there more evidence that the Earth is flat?

That is, in addition to Rowbotham, are there other scientists who will test the flat Earth?
They say that Auguste Piccard saw the Earth flat, but what do you think of this ?:

Are there pictures of the Earth flat?
I would like to see more evidence of those raised here and I would like, please, to answer a fundamental question: how is it that in the northern 'hemisphere' the stars rotate in one direction and in the southern 'hemisphere' rotate in another?
I would like a strong answer to this question, so I myself can irrefutably refute an atheist who asked me about this question. Thank you.

There are may proofs for the flat earth, but there are only a few that the globalists do not have an "explanation" for.

It only takes ONE proof to undermine their ENTIRE premise. If you want to say the earth is round you have to prove it. If you cannot prove it completely then it fails.

Piccard is another example of witness testimony.

Thank you very much for the link, but I did not understand Piccard very well: Did he say or did he not say that the Earth was flat?

yes he said it was flat.
