Captured By Aliens!!!!

I need help! I just got captured by aliens and they want me to tell them about Earth, so I did.

I told them that there's a group of aliens that are already on Earth and they are killing people because they want them to move out of Earth. 

 Those aliens want to burn the whole world. They are also stealing other people things. I told them that they shall not go because they poisoned the people and place bombs in the building so they will die.

I told them not to go to Earth because the other alien's will kill them.
L-I.. WALT write a persuasive writing to persuade my reader about my argument.
