I don't want to interfere with your freedom from your original church, however these claims are inaccurate and may interfere with the freedom of others trying to made sense of scriptures. Its not about planets. Scripture puts Israel forward as the Earth. Its not a planet. Its a country. When canon refers to Earth it is talking about Israel: the nation. That is the earth referred to.This image claims that there are 200+ flat earth Bible verses. Though I think at least a few dozen are very relevant and suggest a flat earth rather than a spherical earth. Or they are related to the sun literally going around the earth (part of flat earth theory).
It does not refer to anything else, not any other countries or other lands. In Genesis the country called Israel is made. It rises from the nations, which are stylistically called the waters. The nations are waters in Psalms and in other references. Israel comes out of them, analogous to Moses who is drawn out of the river. 'Earth' is not scientific and is not about a flat earth. There is absolutely no implication in the canon of anything about a planet, no treatment of our position in a solar system.
Looking at the verses referenced: I see that none of them presume knowledge of a planet, nor a Discworld situation. They are not in pursuit of astrological knowledge. Astrology is rejected in Judaism and considered a form of divination (which is illegal). Any politician claiming astrological knowledge is operating illegally. This makes perfect sense as astrology generally is a means of extortion.
