* Nuclear Fusion: The sun is a giant ball of hot gas. Inside its core, hydrogen atoms fuse together to form helium. This fusion process releases enormous amounts of energy, which manifests as light and heat.
* Reflection: Reflection occurs when light bounces off a surface. While the sun's light does reflect off objects in space (like planets), the light itself is not created by reflection. It's generated from the sun's internal processes.
So, the light we see from the sun is a direct result of the fusion reactions happening deep within its core.
