I don’t believe in flat earth, but I’m exploring it. The assumption Carl and his Eratosthenes, who may or may not have existed, are making, is that the Sun is so far away that the sun’s rays come in parallel. That is already part of the globe earth model, so of course it supports another globe earth conclusion. Have you proved to yourself that the sun is so far away, without relying circularly on a globe earth assumption to prove it?
There is no "globe earth assumption." We've known since the 16th century that it is conclusively round (Magellan's circumnavigation). Why don't you start with the hand's-on evidence and testimony and catch up from there?
Don’t worry, I know everything you know about it. Wow, Magellan, really? I knew about that fully when I was 5 years old. I’ve even circumnavigated the Earth myself. Anyway, I specifically said I don’t believe in flat Earth, so why are you trying to convince me? And why specifically are you trying to convince me simply by telling me the commonly known things, which obviously I know, because it’s common knowledge.
A lot of people don't believe in anything. You might be one of them. If you are "exploring" the idea of a flat earth, and refer to a globular earth as being an "assumption," then you are not knowledgeable enough about circumnavigation to realize that Earth's roundness is a fact, not an assumption.
The radius of the Earth is about 6378 km. The distance to the Sun is about 150 million km. This means the angular separation of measurements of the Sun's direction from opposite points on the Earth cannot be more than about 85 microradians. If the sun is closer, it is possible (inevitable) to get much greater separations. So, go get 'em, since you know everything I know about it.
Keep questioning. Latest Artemis mission vehicle does not appear to have enough fuel reserves by my calculation to do a round trip to a moon as far away as NASA says it is. Same problem with Apollo. This indicates either 1. They didn’t go all the way and just hung out in Low Earth Orbit (LEO), OR 2. It is much closer than NASA says (NASA caught lying at least 40 times by my count)
Consider also that the current size of the Earth may be much larger (diameter) than what was reported a long time ago. I have not seen any modern measurements from anyone other than NASA or geologist liars in last 200 years, so I suspect it has changed and they don't want to report that. This possibly could create the perception that the Earth is flat or flat-er as the curvature may be less than expected given outdated diameter size (this curvature issue needs some hard data by credible people without an incentive to keep lying to us).
The size and shape of the Earth is a subject of constant attention, in order to develop accurate and up-to-date ephemeris information for space vehicles. We have hard data. You just don't want it. You already demonstrate you have no idea what "credibility" means, or who is or isn't. You are not searching for the truth; you are just searching for the pastor who will satisfy your itching ears.

Because only stupid people think the earth is flat.

Correct. I suspect everyone is lying. Still sorting it out.
