We humans got to thinking of developing Mars for human habitation and maybe one day to make animals to give humans company too and how long did it take us as civilised humans to get there? A few thousand years. And you cannot think that some being somewhere would be able to get well beyond that stage even over millions of years to be able to create a home on this planet and while hidden away be able to produce life like us and the rest of our planet occupants for their pleasure and ultimately their company (once we are rwady for it)?
