You seem lost to Muslims, because you don’t believe in Islam. Are they right? Or are they deceived, but they don’t realize it, because their religion is designed in such a way as to prevent that realization? If you were in the same situation, how would you know?
The Bible does not say Yahweh hung a sphere in heaven. It says he drew a circle on the face of the deep, as with a compass (a tool used to draw 2D circles, not sculpt 3D spheres):
NASB, Proverbs 8:27: “ “When He established the heavens, I was there, When He inscribed a circle on the face of the deep,”
KJV, Proverbs 8:27: “When he prepared the heavens, I was there: when he set a compass upon the face of the depth:”
You accept Earth is spherical, but because science revealed that long before you were born, not because it says so in the Bible. Because you assume the Bible cannot be wrong, it follows in your mind that the Bible cannot be describing a flat Earth covered by a solid dome (the firmament) no matter how much it appears to, and no matter how many historians and Biblical scholars agree that’s the model of cosmology ancient Hebrews believed in.
You are not allowing for the possibility the Bible is wrong about the shape of the Earth for the simple reason that Christianity is false, and as such, scripture was not revealed by a higher power. It was the best guesses of humans alive at that time, hence why their cosmology included a flat Earth, just like the cosmology of the neighboring Egyptians and Babylonians at that time.
Galileo (not “Galalo”) was persecuted by the church, something you conspicuously left out. You also seem to be under the impression that Galileo lived at the same time as the authors of the Bible. That is not the case, very different time periods. When the NT was written, there was no science because science as a discipline is descended from natural philosophy, which also wasn’t formalized yet. There were “attemps to figure out nature” but that by itself isn’t science, science is more rigorously defined than that (see: the scientific method).
Regarding your statements about queer people now being called gay, that’s unsurprising talk coming from a Christian and a big part of why people are leaving Christianity in droves. I hope one day you’re among them and we can return to this discussion as equals.
