Why is this the answer?

The answer is log because this riddle uses clever and imaginative words to describe a piece of wood that is burned to make a fire. To understand the riddle, we can look at the two big clues it gives us. First, the riddle says, "I am dead before you lay me in your hearth." A log comes from a tree, which is a living thing. When a tree is cut down and turned into a piece of firewood, it is no longer alive, even though it still looks like strong wood. The word "hearth" is just a fancy, old-fashioned name for the stone or brick floor inside a fireplace where a fire is built. So, the log is dead wood before you ever set it down to burn and keep your house warm. The second clue is the most interesting part: "In your fire you hear me scream, creaking and whining." Of course, a log does not have a mouth and cannot really scream. This part of the riddle is describing the noises you hear when a piece of wood is burning in a hot fire. Even after wood has dried out, tiny bits of water and sap are still trapped inside. When the fire's heat warms up the log, this leftover water quickly turns into steam. The steam needs a way out, and as it forces its way through the wood, it causes the air to make a tiny popping or crackling noise. These quick bursts of sound are what the riddle poetically calls "screaming," "creaking," and "whining." This means the answer perfectly matches all the clues. The log gives us a warm, bright fire, and those crackling sounds are the wood's way of telling its story. A log is the best kind of fuel for a fire because it burns slowly and helps us stay cozy on a cold day. It is an everyday object that has a secret, noisy life once it meets the flame.
