The day we saved Earth

In the year 2020, a lot of things were going on. Humans on Earth were going through a lot of problems during that year. But those things were nothing compared to the enemy that will take over there home planet. One day, an unknown species came to earth. They called themselves, “ the Coronas”. The Coronians ravaged the Earth and killed millions and millions of people. By the next week, 80% of humanity was gone. And so, they decided to leave Earth. The humans built special spaceships and the humans immediately left Earth. 20 years have passed since then and now human technology has developed. But, some of them missed their old home, Earth. And there was this one girl that wanted to change everything and finally take back their planet. Her name is, Alister Nash.
