Why is this happening (apocalypse au)

Aliens had invaded, millions of people died each day, the apocalypse was happening, people were being turned into zombies left and right, and on top of all of that scientists were experimenting on people to make them immune which caused even more problems. The leaders of the apocalypse were merciless and showed no mercy. The leaders were a team of aliens who the other aliens called the SBI, Dream Team, and beeduo. They all worked together for king Philza, queen Kristen, prince Wilbur, and prince Technoblade. Tommy innit was a young boy who had lost his parents to this apocalypse. He's fended for himself through the entire thing and has yet to get caught. He was One of the few surviving people who were experimented on. When he does get caught he has no idea of what's about to happen.
