[ WP ] Humanity is feared throughout the galaxy for their use of kinetic weaponry . Something no other species has developed .

Imagine the caveman, with his sloping brow and clumsy hands realized that chunk of rock could be hurled at his enemies. The light that dawned insider his primitive mind. He was powerful now, as the giant ball of fire that rose over the horizon. He could smite his enemies from a far, training his brethren to do the same. 
 
 Time marched on. To the Mongols perfecting the bow and arrow, to the use of Chinese gunpowder to make bits of metal turn from harmless knickknacks to flying death, humans continued to perfect weaponry until the day the first ship landed. 
 
 It was nothing like the movies. The ship did n't land in front of the UN or White House or another cliched landmark but in a farmer's field in Northern Alberta. The ruby metallic sphere hovered a meter of the ground for days as crowds gathered. From fans to military, scientists to doomsdayers. The biggest congregation ever. 
 
 When the ship opened on the 23rd day, a being floated out. He, if you can call it a he, looked unnatural. It more crawled out of its ships, it's hide more akin to a rocky slope. Veins of something forest green burned on the top of its carapace. It had no limbs to speak of, but instead the green tendrils crawled out of its skin and used it to propel itself around the cordoned off area around the ship. Camera flashed and people spoke, but the creature did not react as it made a slow circle. 
 
 No one knew who fired the gun. Most blame a crazy cultists as the bullet went flying into the creature. There was a hiss like steam from a geyser, the tendrils flailing for a brief moment. Then all was still. The alien hissed and slowly dissolved into nothingness, turning the wheat around it to a blackened ash. 
 
 That was five years ago. The aliens came in waves now, non stop. They would leap from their ships, green appendages flailing. But.. they seemed to have no concept of a simple gun. Even the most basic grazing shot would take down these creatures from the stars. It became a sport even. Another ship would arrive, in the middle of the Gobi desert, the rocky mountain range, all over. Hunters would rush out for sport, taking trophies. We considered ourselves gods as we easily routed these pathetic invaders. 
 
 
 We at first considered these aliens foolish, simple, ourselves more powerful than these starcrossers. Until we realized something. Every alien killed salted the Earth under it. The land was dying. Trees had withered to broken husks. No land would grow any crops. The cities and forests both were nothing but graveyards. I had barely survived, eating expired peaches from cans when, one day, I saw a new ship arrive in the center of what was on Cleveland. Not the scarlet ships of our invaders, but this one was a bright silver disc that shimmered in the dusk. I rushed out, perhaps desperate for a savior. `` Please!'' I cried. `` Help us, we're dying, these aliens are killing us. Please, can you stop them?'' 
 
 `` Aliens?'' A clearly synthetic voice answer a moment later. `` Foolish parasites. Ca n't you recognize a weapon when you see one?''
