Why is this the answer?

The answer is ball because this clever riddle uses fun word pictures to describe one of the most common and exciting toys in the world. It is a puzzle that tries to trick your brain into thinking about a person or an animal, but the answer is actually an object that is part of almost every game we play, from kickball to basketball. Let us be detectives and check each clue in the riddle one by one to see how it points perfectly to a ball. The first clue says, "I can be moved. I can be rolled." Think about your playground during recess or your yard at home. What is one of the easiest things to move simply by kicking, throwing, or pushing? A ball, of course! Because of its perfectly round shape, you can easily roll it across the grass for a game of soccer or bounce it around on the pavement for four square. The next part of the riddle is a clever puzzle: "But nothing will I hold." This means that a ball is usually a solid object or one that is filled with air, so it cannot carry anything. It is not like a bowl that holds your cereal or a backpack that holds your books. Its only job is to be bounced and played with, not to hold other things inside. The third clue is about its appearance: "I'm red and I'm blue, and I can be other colors too." You know this is absolutely true! You have seen bright red dodgeballs, blue basketballs, and even fancy balls with stripes and stars in every color you can imagine. The last clues help us see why it is not alive: "Having no head, though similar in shape. I have no eyes, yet move all over the place." A ball is perfectly round, which is similar to the shape of a person's head, but it is just made of rubber or leather, so it has no real head and no real eyes. Even without eyes or legs to see or walk, it moves all over the playground and the court because you and your friends are always there to kick and throw it. That is why the ball is the perfect solution to this riddle.
