What if there was civilization on Venus an ego ago, a civilization that either evolved into a higher form or fell extinct? A billion years later, there is no trace remaining.
Or perhaps far in the past, a civilization on Venus escaped the malfunctioning of its environment by seeding life here, the next planet outward from the sun. So far there's no clue about how terrestrial life began. Darwinian evolution suggests how organisms that already exist form new species, but Darwin was silent on what created life. Microbes came into being nearly 4 billion years ago, but complex animal life appears to have begun relatively rapidly between 530 and 570 million years ago.
Maybe that was the time a Venusian civilization was dying. Maybe we find no clues of the origin of complex biology here because this process began on Venus.
Or perhaps you are a fucking hack who has no idea what the fuck you are saying?
