[ 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

Our planet was exhausted. Not in a figurative sense, but literally exhausted of resources. We had created a near perfect society, almost a utopia, where the idea of one's needs not being met were archaic. We were able to do this because we had such introspective focus after the First Collapse. The wars on the Aegin peninsula and Domsette region, which were followed by horrible natural disasters of hurricanes and volcanic activity, made people panic and act irrationally, letting the Plague spread. 
 
 No food, people dying on every road, it was a global catastrophe. Intelligent life almost faded from our planet, but luckily an early version of the Council was formed. They called themselves Overcomers then, as a symbol of our race's will to overcome desperate times. Their goal was simple: to eradicate everything that posed a threat to our survival. They lead us out of the grasp of extinction and into the Age of Discovery. Science took leaps and bounds forwards in medicine, machinery, travel, but many separatist views were extinguished. In the last few decades before the Second Collapse the council had become more open to alternate ideas and became more open to individual freedom. 
 
 Unfortunately, it was too late. Societal focus had been too heavy on providing for everyone. Council-sponsored organizations had done great things, inventing cures and preventative measures for all types of diseases, making homes that were resistant to natural disasters, and all manners of infrastructure built across the globe. But no one was tasked to manage our resources until personal liberties were expanded, and even then it was years before anyone noticed that we had so little time left on our clock. 
 
 The Council tried to mitigate the effects, but to ensure our survival as a species, they themselves implemented the Second Collapse. By sentencing 90 % of the population to cryo-chambers, they gave us time enough, with the resources we had left, to find another home. And find another home we did, on a planet they called'Earth'. It was the only planet we could find in time that could sustain us, that we could manage to live on. So we set a course for Earth, to save us and our sleeping kin. 
 
 We sent a message to these Earth people that we were coming to colonize them. That we saw they were intelligent, so we were giving them a chance to leave if they wished. It would take us roughly 100 years from an observer's perspective to get to the planet, but much less actual time for us. This is why my account is rushed, because we have no time left on this vessel. While we planned to systematically annihilate hazardous life on Earth with specialized biological strains, the humans of Earth have taken a much different approach to combatting us. Somehow, they created empty vessels for redirecting mass in space that can then accelerate to any destination. At this moment, asteroids are hurtling towards our craft and our planet. We can not take preventative measures. Neither will survive the onslaught. 
 
 I do n't know what kind of peaceful species could be so cruelly clever as to devise such massive weapons for this purpose. Maybe you do n't truly grasp the weight of the billions of lives you are extinguishing because you've never had to take intelligent life before. These are foolish hopes of a dying race. We know you are a violent people, so know this of us: we were n't the first intelligent race on our planet. We emerged from their ruins. The dominant species of our planet sent themselves to their deaths with weapons like yours. We of planet Caeath can only hope your day of reckoning comes soon.
