This may be a little confusing, but I thought it would be fun: At the end of the movie A.I. (not the greatest movie ever, but go with me on this), humanity has died out and a race of machines is studying what once was the human race. They can easily resurrect specific humans from the past, including their memories, etc. Now using that concept as inpsiration, lets say you were in charge of building a new human civilization on a new planet (or in a new dimension, whatever). The only requirements would be to manage an eventual population of 5 billion or so that can exist together and evolve. The world would like the world today, with similar climate and and natural resources as well as the same basic geographic layout. To set this in motion, you can only use a single human's brain- with all of its information and abilities- to construct or reconstruct humanity. All humans will be based on this model. Now the question is who do you use? This can be a specific person, ie Albert Einstein, or a generic type of person, ie a physicist. Do you use someone like a professor or mechanical engineer? They know plenty of principles but do they have enough real world experience to implement all of the systems necessary for a productive world? Remember, your humans have to learn how to speak, how to write (if you want them to), where to put waste, how/who to marry (or not), what to believe in (and whether that can change), how to make fire, how to build a house, etc, etc, etc. Also, do you build a simple society, like one based on agriculture, or do you go for a complex modern society with computers, transportation, etc? Do you set up a unified world? Or a group of independent countries? Do your people sail the seas or power across them with engines? Solar power? Fossil fuels? So, who would you use and what would they do? Sort of like a giant game of the Sims.
