[ WP ] Aliens come to Earth in hoping to wipe us out and take over the planet , but are honorable and gives us a fighting chance . They announce they will return in 100 years so as to give Earth a chance to prepare and defend itself . Neither side expected what the other would bring to war

The initial invasion was a disappointment. It was over before it started, and we did n't even get the chance to die heroically. Then they were gone, their only trace: a single warning and that lingering rage that comes from realizing you are powerless, trapped on a speck in an infinite empty universe with nothing but silent indifference for you. We had 100 years to try again. The pace on Earth changed quickly; no longer did we drift aimlessly through space, but instead we were animated with a true purpose. Political conflict was swept away like trees before an atomic blast. Our ancestors realized that we are makers, and our salvation lay in creativity. Now that every mind was essential, hunger and poverty were eliminated with embarrassing ease. Breakthroughs came immediately. We developed ships and weaponry, and within fifteen years had flung ourselves out of our solar system. Colony ships were sent out as an insurance against extinction, but we were n't fleeing this fight. Work went into genetics and artificial intelligence to improve ourselves or build consciousnesses that could discover with us. Traditional morals were bent, broken, and then abandoned. Human genetic testing began at the end of the second decade, and a new type of artificial intelligence emerged. No longer did we try to replicate human brains, but instead we grew a machine mind with genetic code, and let it take whatever form it needed. A.I. rebellion was deemed an acceptable gamble, and when they finally arrived, their brilliance and earnest companionship convinced us it had payed off. As progress accelerated, our grim determination softened. We had discovered more in a generation than we had in our entire existence, and excitement crept into the corners of our minds, then pride. Our genetically enhanced offspring stood together with our new machine comrades, the most promising and capable humans ever to have existed, and now with a clear indisputable goal: to fight and to win. It was our moral compass, our religion, our purpose. We spent the last few years checking our work, making certain there was no last area of science we had not fully explored. We could find nothing left to do but steel our minds and await our test. As our judgement approached, we celebrated our history, our progress, and our accomplishment. On the final day, a million hearts at a million battle stations beat with excitement. The clock hit zero and began counting up, every second of our new era bought with our willing sacrifice... or a time-keeping error relating to exactly when they gave their ultimatum. And then there was void, nothing left to be done and no more worlds left to conquer.
