Ok kiddo, so some people really love and admire the sun a lot. They think it's very important and powerful. They call this "sun worship". It's kind of like how you might really love and admire a superhero or a favorite toy.
People who practice sun worship usually do things like pray or give offerings to the sun, or they might have special ceremonies or rituals to celebrate it. They believe the sun is very important for life on Earth, because it gives us warmth and light, and helps plants grow so we can have food to eat.
But it's important to remember that different people have different beliefs, and that's okay! Some people might worship the sun, while others might worship other things or have different beliefs entirely. What's most important is that we respect each other's beliefs and ideas.
