The planet would survive but humankind was probably doomed. There was indeed a solution but it couldn't be finished in time to save civilization. So they built what they could and left artificial intelligence to finish the job in the hope that any survivors would need it in the future. Assuming that their descendants would have the scientific knowledge to make use of their creation there was still the problem of how language would change over 12,000 years. They built Atlantis, left a code, and hoped for the best. Now a small group of scientists has less than a week to crack it. They will need to venture under the ice of Antarctica in the middle of a war, escape nanoswarm lifeforms that would prefer humans die out, and crack the code that might explain how to use a machine beyond their science.
