Why is this the answer?

The answer is horizon because this is a beautiful riddle about something amazing you can see every single day just by looking far into the distance. Think about being in a very big, open space, like a park, a huge, empty field, or when you are standing next to a large ocean. When you look far away, you can see the special line where the land or the sea seems to finally meet the sky. That dividing line is what we call the horizon. This perfectly matches the first clue in the riddle: "When you stop and look, you can always see me." Now for the next part: "If you try to touch me, you cannot feel me." This is a helpful clue because it lets us know that the horizon is not made of anything solid. It looks like a real line painted across the distance, but it is actually an illusion created by your eyes and the shape of our planet. It represents the farthest point you can see before the Earth’s curve hides everything else from your sight. Since it is not a physical object, you cannot put your hand out and touch it, which is exactly why you cannot feel it. The final and most ingenious clue is: "I cannot move, but as you near me, I will move away from you." The horizon itself does not go anywhere, but if you start walking toward the line you see, it will seem to shift away from you as you walk. It is a trick of perspective. You will never actually reach that spot where the sky and land meet. The horizon always stays the same distance from you because you are constantly moving and seeing the farthest possible edge of the curved earth from your new position. It is always there for you to look at, always beautiful, and forever just out of reach. This makes the horizon the perfect answer for this very clever riddle.
