Ah, but the horizon is always flat. On any point on earth, no matter how high you are, the horizon is completely flat. All amateur balloon, rocket, plane and drone footage show a completely flat horizon over 20+ miles high.
As for the rotation, I'm afraid if that's your only proof your going to be sadly mistaken. Because what you said has two options. Either the earth is still and the sun rotates above or the earth itself is spinning and the sun is still.
When I asked you to prove the rotation, you gave an answer that fits the flat plane earth. The goal is to find a proof that exclusively fits the spinning earth theory.
2 + 1 = 3 but also 1+2=3
I can find hundreds to support the flat Earth exclusively
