Why is this the answer?

The answer is sunlight because this super clever riddle is talking about something we see and feel every single day, and it uses brilliant word tricks to describe it. Let us look at all the clues one by one to see exactly how they fit the answer. The first part says, "I appear in the morning. But am always there." When the sun rises in the sky, we see the bright sunlight streaming all around us, which is when the light "appears" to us on Earth. But the sun, which is the source of all that light, is actually always "there," shining brightly in space, even when it is night on our side of the planet. So, the riddle is playing a clever game by talking about both the star and its light at the same time. Next, the riddle says, "You can never see me. Though I am everywhere." This is a fantastic and tricky clue. You can see the amazing results of sunlight, like the beautiful colors on a butterfly or the shadow you cast on the sidewalk. But the actual light rays themselves are a form of invisible energy. During the day, that light is spread out and is "everywhere," filling your room and the entire sky, even though the energy itself cannot be seen. Then, we read, "By night I am gone, though I sometimes never was." The sunlight is always gone at night because the Earth spins around and blocks the sun's direct rays from reaching our location. The part about "never was" is a very smart addition. It reminds us that sunlight may never reach a certain dark spot, like deep caves, or when you are inside a completely dark closet. Even during the day, if you are in a dark space, the sunlight "never was" in there with you. The final clue is, "Nothing can defeat me. But I am easily gone." Nothing in our world has the power to stop the sun from shining. The star itself is too powerful to be defeated. However, its light is "easily gone" or blocked just by putting up a simple wall, a roof, or even placing your hand over your eyes. This riddle is a wonderful way to think about the powerful yet delicate nature of light and the big star that gives us our day.
