I have a question about Earth millions of years ago.
If there were advanced spacefaring civilizations on Mars and Maldek millions of years ago then why was the Earth an undeveloped primordial world? It seems to me that it would have been settled for its resources at this point, given the need for them by nearby civilizations. The Farsight projects say inhabitants of these planets only moved to Earth after destroying their own planets. Wouldn't it have made sense for at least one of the other civilizations to have already have had a presence there?
There could be some reasons for Earth being undeveloped while Mars was bustling. Maybe the climate wasn't right. Maybe it was a neutral zone. I don't know. It just seems like there wouldn't be a jungle/desert world in a solar system with skyscrapers and interplanetary spaceships on other planets. Thoughts?
