We hide in shadows. Our planet is lost. We are the last humans, and we must go home. Two thousand years ago, aliens destroyed Earth. Our fleets shattered. Billions died. The last humans fled a burning planet, heading to the stars. Today we are still refugees. Hungry. Afraid. Our enemies hunt us everywhere. So we hide. On distant asteroids. In rundown space stations. In deep caves on frozen worlds. And we dream. Of green hills. Blue skies. Golden fields. We dream of Earth. And for the first time, we have hope.

The galaxy burns. The enemy, a race of alien scorpions, storms from star to star. Planets smolder in their wake. Across the galaxy, they hunt humans. Long ago, we humans had a planet of our own.

We must fight the scorpions. And we must find Earth! Only Earth can unite us. Only Earth can kindle our hope. Only on Earth can we defend our species.

The basilisks, cruel alien serpents, attacked our world. They bombed us. Hunted us. Butchered us without pity. But now we will be the hunters. We will assemble a fleet. We will cross the vastness of space. And for the first time, we will strike the enemy on his own soil. It's a time for courage. A time for heroes. We will no longer hide in bunkers. We will no longer die like sheep. Freedom will be won with blood and fire. Freedom will be the legacy of Earth. We are the last humans. And we will win!

On Earth, we can rebuild what we have lost. Earth is but an echo, calling from beyond the darkness. We will answer her call. We will find our lost world. We will defeat our enemies. We will rise again!

Powerful politicians like Senators Mitch McConnell and Jim Inhofe, who receive massive contributions from the oil and coal industries. Most of these men are too intelligent to truly believe that climate change is not a growing crisis.
