[ WP ] aliens invade earth but what the do n't realise is that humans have been fighting each other forever and have become very good at it .

Admiral Calix stood ready to give orders, his reputation was that of responding to the unforeseen. 
 
 `` Admiral, fleets are in position, shall we establish contact'' 
 
 `` Yes, it is time we bring our demands to these simian scum'' 
 
 Dreadnaught class warships landed on their pathetic Earth, dwarfing their greatest seafaring vessels. The demands were simple, servitude and resources. 
 
 The humans had refrained from attacking, not knowing if their visitors were hostile. But now they knew. Now the response was imminent, and well prepared. 
 
 Our numbers were massive compared to their primitive armies, our technology made them comparable to the cave humans our race observed millennia ago. There was something we missed. Their tactics were incredibly refined. A few humans with a few primitive weapons driven by explosives. Explosives! The worthless apes still used explosives! Were enough to find and exploit the weakest points in our ground formations. 
 
 Their ships arranged themselves in preparation for assault from all angles. Geometric patterns artfully designed in anticipation of our greatest maneuvers. 
 
 We fought a long and bloody war that decimated our forces, our casualties dwarfed theirs like the great vessels we once thought meant so much. They drove us off their planet and back into the void. 
 
 We waited for centuries watching their planet, preventing them from leaving. These apes of war had too much potential. They were too dangerous. Then the unthinkable happened. They responded to our blockade. They attacked with our technology, they learned from our mistakes. Their forces once more were fractions the size of ours, but they had our technology, and we did n't compare to them when they did n't. 
 
 We had made so many mistakes, and they were about to kill us all for them. We had unleashed a scourge on the galaxy, and we would be its food and fuel.
