I am a 15 year old writer and was wondering how can i make this more original?

Ten thousand years ago, many light years away from Earth. A planet named Dragon World with many similarities to Earth such as the life of humans and bazaar creatures like trolls, giants, dragons, snakes, and huge lizards. For thousands of years the people and nations of Dragon World lived in peace and prosperity, until a dark, immortal, evil human named Theris started to destroy homes and villages. Now, Theris and his followers are destroying all the nations that are left on Dragon World. Their main goal is to unleash the three legendary dragons who are the most powerful dragons in that had ever existed, in order to destroy the last great city that stands. For now, the only one who can open the tomb and release the dragons is the savior. One last hope belongs to a seventeen year old boy named Max Leoguard who is unaware that he’s the savior. Max is the only one that has the power of killing Theris and his followers, in addition, to releasing the three legendary dragons. Now Max and his friends must go on an epic journey in order to defeat the two followers and Theris, in order to save Dragon World from certain destruction.

I know this summary might sound like a story that has been overdone, but once you read it is alot different. I am really bad at summarys.

I have not read Eragon, but have read the summary and can insure you this is way different. There are a lot of deep plots that go on within the story itself

You don’t have any worries that it is original, because it is. Some comments though: Ten thousand years ago is less than a wink when you are comparing it to light years. Bizarre is the spelling you want. I can’t figure out what tense it is supposed to be in. Savior probably should be capitalized. Hope doesnt belong to the 17-year old. He is the hope. Too many commas in the sentence starting "Max is the only one….." Would read better as "Max is the only one that has the power of killing Theris and his followers, as well as being able to release the three dragons. When did Theris go from followers to "two followers?" Good luck
