You have yet to explain WHY we see in perspective. I think it is important to understand how the human eye works so that you can determine if the human eye can be trusted to accurately reflect the world around us or if it ha limitations that force us to go beyond what our eyes are telling us.
You are not starting from the ground up. Your title to this thread rather demonstrates that. You have stated in your title that the Earth is flat and that we never went to the moon. You have made conclusions and you are trying to support that to the point where you absolutely ignore any question that really forces you to look at the flat Earth model.
Sunrise and sunset - Flat Earth says the sun and moon are rotating above the Earth in a plane parallel to the Earths surface. This path does not explain why the rises from the top down, sets from the bottom up and is always the same size throughout the day. You have been asked to verify this yourself, you have been given methods to do so yet you have not done ANY investigative work of your own. Why?
If the sun is a "spot light" circling above the Earth and only about 3,000 miles up, why can't we see it at night? The sun would always be visible from everyplace on a flat Earth because there is nothing to block it. You may not be under it's light, but you would still be able to see it. If you take a really bright spotlight and suspend it from a pole so that it points at the ground, you can mimic the problem. If you stand under the light, you can see it. If you walk down the block, or even two or three or four blocks, you can still see your spot light but you are not being illuminated by it.
Unless and until flat Earth "science" can produce a repeatable experiment that is peer reviewed and accepted by existing scientific journals, you cannot make any meaningful claims about, well, anything regarding the flat Earth. You may not like the part about submitting to existing scientific journals but that is what every other person who has and idea about how the universe works has to do. I am holding your movement to the same standard.
I stated recently that I was going to methodically start from the ground and work my way up, as per the video, "Proving the earth is not flat--Part 1 Horizons", because we were jumping all over the place with video vs video when I first started this debate.
I have and will again provide video of the sun changing size from sun up to sun down. I have explained why we see the sun do what it does on a flat earth viewed with perspective. You simply don't accept that explanation. That we all see the world in perspective is a fact not a theory. A fact that globe earth must deny.
What we all see, and don't have to investigate, is that the sun, moon, and stars all move above us just as the clouds, birds, and planes do. We never sense in anyway the earth spinning. We never see a curvature that's admitted to be too far away to see anyway, but that we do see the horizon of a curved earth we look ever so slightly down at (that it's so nearly at eye level we can't tell the difference) just three miles away is mind boggling.
As to the size and distance of the sun from earth I have not said. But in perspective everything that moves across the sky will disappear at the horizon regardless of how high up it is or how large it is.

We don't have to be scientists in order to understand the contradictions in the globe earth model. Tesla was very clear that electromagnetism, not gravity, explains our world. He accused Einstein of departing from actual experiments and relying on thought experiments--imagined theory, instead. Flat earth research must submit to a peer review by globe scientists??? That's a good one, I'm glad someone else here has a sense of humor.
"I think it is important to understand how the human eye works so that you can determine if the human eye can be trusted to accurately reflect the world around us or if it has limitations that force us to go beyond what our eyes are telling us."
Please do elaborate on this. This is where all deception begins, "why we cannot trust our senses". I'm glad you brought it up.
