That's almost right! It's not exactly reflection, but rather scattering and absorption. Here's the breakdown:

* The Sun emits light: The Sun produces its own light and heat through nuclear fusion.

* Light travels to Earth: This light travels through space as electromagnetic radiation, reaching Earth.

* Atmosphere scatters light: The Earth's atmosphere, mainly composed of gases like nitrogen and oxygen, scatters sunlight in all directions. This scattering is what makes the sky appear blue.

* Some light is absorbed: Some of the sunlight is absorbed by the Earth's surface and atmosphere, turning into heat.

* We see the scattered light: The scattered light reaches our eyes, making the daytime bright.

So, while the light isn't simply reflected back to us, it is scattered and reaches us from all angles, giving us daylight.
