Because of the rotation the earth faces the sun at daytime but when it rotates again it faces away which makes night.
No, our eyes does not give out light. Only light comes in to our eyes allowing us to see.

The Big Bang did not give us visible light. Light, from the time of the Big Bang has been red shifted so that it is now in the microwave part of the spectrum.However, the Big Bang did give us all the matter that exists, and some of that matter formed stars which, in their nuclear fusion, produce light.
The sun gives us light, it makes our plants grow, it gives us warmth and it gives us energy.
No, because gravity has to do with mass, not rotation. If it weren't for gravity, the rotation would cause people to fly off into space. Every object is supposed to go in a straight path forever, unless countered by another object. For example: If you have a a circle, with a small opening (_) (but with the bottom slightly more rounded), and you put a marble inside and gave it a slight push, it would go around the ring, till it reaches the opening, where it will leave in a straight path. The thing stopping it is the ring, exerting an inward force on it. The Earths rotation is pushing us in our natural straight path, and gravity is like the ring, stopping us from leaving by exerting an inward force on us towards the center of the Earth (the surface is keeping us from going to the core; the surface of Earth acts as the ring, also pushing an inward force on us , which to us will push us out. However, gravity keeps us from floating, for being so strong. The gravity is so strong because of the close distance between us and the Earth, plus the Earths mass is very large). Anyway, rotation causes us to leave Earth in our natural straight path, and Earths gravity keeps us here; henceforth, Gravity and Rotation have nothing to do with each other. I apologize if there is any mistakes (probably not, but perhaps). I am not a teacher nor an adult, so it is plausible that I have some information wrong, nothing major, but perhaps a few words here and there are incorrect. It should be overall correct.
Yes, the Earth's rotation on its axis is what gives us day and night. As the Earth rotates, different parts of the planet are either facing towards the Sun (day) or away from it (night). This rotation takes around 24 hours to complete, creating our daily cycle of light and darkness.

No
These combined give us day and night, and seasons.

Light? Heat? Nice things?
because they reflect the suns light, so they become visible to us. they twinkle due to the earths atmosphere blocking out some of the light.
