1. You can see the sunspots yourself using a pinhole camera projection of the sun.
Looking at a cells through a microscope, you will see moving spots as well. The slide is not a burning ball of helium 9.3 million miles away. Also, do you know how DLP TVs work?
2. Likewise, through spectral analysis of the eastern and western limbs of the sun you can measure a difference in doppler shift - one limb is blue shifted the other red shifted.
There's no reason this cannot be accounted for by reflection. In fact, reflection makes it quite a bit more intuitive to explain.
3. Again, by looking at absorption and emission lines you can tell what elements the sun contains - this is how helium was discovered - which turn out to be hydrogen and helium. Also we can detect neutrinos from the sun, which come from the fusion reactions.
It seems that the data that you have provided tends toward a spotlight Sun reflecting and focusing the Earth's luminance even more conclusively.
1. Perhaps I was unclear here. I was trying to show that the Sun has structure and is not just an undifferentiated light source. But maybe that's an unwarranted assumption. You can also view sunspots as another proof of the sun's rotation since their movement can be tracked.
2. I don't see what reflection has to do with it. Doppler shift indicates movement toward or away from you. This is easily measured and you can even work out the speed of rotation.
3. I haven't actually provided any data, I'll leave that to you if you want to verify it for yourself. The data would show that you're looking at a glowing ball of hydrogen and helium. Since you haven't even clarified what the Earth's luminance is I don't see how this helps your position.
Again, nothing you have said so far is backed up by any contrary evidence, and does not explain the existing evidence.
