Humanity's scientists thought that life in space really existed, so they thought about sending a message on the outer space. Actually, not every scientist. 90% thought that the idea of life, actually existing in the outer space was stupid. 5% thought that was actually true, but sending a message was stupid. 3% didn't even care about it. And the last 2%, actually sended the message.
Unfortunately for them, the aliens, or other sentient beings (as the 2% called them), responded to the message. And they brought an entire fleet of spaceships and an army to conquer earth.
Humanity was driven to a corner, and lots of people died, but hey! With the arrival of the aliens, they also brought the possibility to humanity to fight back!
But how it turned out?
