Riiiiight, Copernicus.
How about what can be seen with your own eyes?

Yes, like when you see the sun rise at the eastern horizon, arc overhead across the sky all day, then slowly disappear over the western horizon each night.
If the earth is a disk, the only explanation for that observation, is that it's oriented on edge to the sun. It means that the entire surface of our world is in daylight at the same time, and that during our night the reverse side of the disk is illuminated.
But we know this isn't the case, because half of our world is always in daylight, while the other half of the surface is in darkness.
That is only possible if our planet is a sphere.
Look with your ow eyes at the changing phases of the moon, and explain how that observation squares with the theory that planets and moons are disk shaped objects. It doesn't. Your direct observation disproves the theory. That is, unless your beliefs are so strong that they override your basic senses.
Nope, Apollo had an ablation thermal protection system, which caused a phase change of the material, and emitted hot gases, keeping the remaining material relatively cool compared to Shuttle tiles.
Also, the Apollo was on parachutes for the last 40,000 ft, which allowed the remaining material to cool even further.
