About 100,000 years ago, the entire subspecies of Homo sapiens sapiens -- all of our ancestors -- consisted of about 2,000 to 5,000 individuals living around the Rift Valley in Kenya. What if they had built museums of their art, culture, and science, parks, gardens, temples, and libraries that had been preserved ever since? What if all of life had also originated there and spread out since then, and the ecosystem there was by far the oldest in existence? I don't doubt there might be many of our descendants who think or know little of the Earth, but I think there would also be various causes for enduring interest among many.
