Why is this the answer?

The answer is tomorrow because this clever riddle uses special word pictures to describe the day that is always coming next. It is a puzzle about time, which we cannot see or touch, but we always know it is there. Let us be time detectives and look at each of the clever clues one by one to see how they all point to the correct answer. The first line of the riddle says, "I never was, am always to be." This clue is a tricky way of talking about the past and the future. Think about today. The day called "tomorrow" has not happened yet, right? When we talk about things that already happened, we say they "were" in the past. So, tomorrow "never was" a day we already finished. But it is always true that a new "tomorrow" is going to happen, and it "am always to be." It is the constant promise of a brand new day that is always waiting for us just around the corner, which makes the whole idea of a future possible. Next, the riddle says, "No one ever saw me, nor ever will." This is a tricky clue because you might think it is something invisible. You can only see the day you are in, which is "today." As soon as the sun rises on the day we were calling "tomorrow," we stop calling it "tomorrow" and start calling it "today." It is like a magical name change that happens every night while we sleep! Because of this, no person can ever actually look at a day called "tomorrow," even though we know it is coming. It is a day we always look forward to, but we can never actually catch it in the present moment. Finally, the riddle says, "And yet I am the confidence of all, To live and breath on this terrestrial ball." This part means that the idea of a new day gives everyone hope and helps them live their lives. Think about how you plan to finish a big homework project or build a special toy. You know you have time because "tomorrow" will be there. This sense of confidence that the sun will come up again and bring a new day helps all of us on Earth (this terrestrial ball) feel happy and safe to make our plans. The riddle is a beautiful way of saying that the future is always full of new chances and adventures for every single person.
