What if our system got colonized and started on Venus then moved to Earth and now we're getting ready for mars? (This pointing to the greenhouse effect) And could there be structures on Venus we just can't see? Or have we done enough scans that if there were we would already know? Then again life started on Earth ~4 billion years ago so I guess any structures there would be long gone especially considering the heat.
