Why is the sun in the sky red?

Why is the sun red? Scientists will say, "Because this is a law of stars, the color of stars will change color with age." Admittedly, this is correct, but in my opinion, this is not the case. He is popular because he has a heart of self-sacrifice. He injected his energy into the whole solar system. Every morning, we sleep together, and the sun is already hanging in the sky, giving us his blood selflessly. What was he doing that night? Blame it on the round earth. People, birds, cats and dogs living on the other side of the earth are still in the dark. The sun doesn't give the moon enough energy. He went to the other side of the world, but what about this side? The sun didn't forget. He gave the moon and stars a little energy. This will last until the next morning. The reason why the sun is red is that there is another reason besides his self-sacrifice for others. Because he still has a loving heart. In winter, the sun is far away from everyone, because the earth is naughty and far away. As soon as the sun leaves, the temperature on the earth drops, often reaching several degrees below zero. The cold wind roared and the snow alternated. If it's just snow, it's too late to like it, because we can make a snowman and have a snowball fight! However, the power of snowstorm turns beauty into ugliness, and the hateful storm will hit snowflakes on the earth and blow them to people like stones. The original white snowflake, incited by the wind, turned into a criminal bullet. But the sun, although far away from everyone, the more so, the more he wants to help people and help everyone. The love of the sun gives strength and makes the sun redder. He exudes all his strength. Although the weather is still a little cold, the love for the sun is also exciting. Why is the sun red? Because it is a contribution!
