Why is this the answer?

The answer is thunder because all the wonderful clues in the riddle perfectly describe this loud, powerful sound we hear during a storm. Let us look at the first part: "Fatherless and motherless." This means the answer is not a person or an animal that has parents. Thunder is a sound that comes from the sky and the clouds, but it is not born from a mommy and daddy; it is a natural event that just happens as part of the weather. The riddle then says it was "Born without sin." This is a clever way of saying that thunder is a pure, natural thing. It is not a creature that can choose to be naughty or nice. It is just a part of nature, like rain or the wind, and it has no choices to make. Now for the most exciting part: it "roared when it came into the world." This clue is a fantastic picture of the noise thunder makes. When lightning flashes, it heats up the air around it super fast. This makes a giant burst of sound. The sound is so big and powerful that we call it a loud roar or a great boom! The last part, "And never spoke again," is a tricky clue. Thunder makes that big booming noise, that amazing roar in the sky. But after the clouds pass and the storm is over, the thunder does not talk or whisper words like a person. It only makes that one kind of loud, deep, roaring sound. That single, powerful sound is its whole "life" in the riddle. When you put all the clues together, they point right to thunder. It is a natural sound that is not born from parents, is pure because it is just nature, and makes one magnificent, loud roar.
