"I get that the solar system wasn't structured the way it is now. There was a time when all the planets were clumped together, the orbits much smaller. They were closer, but the orbits worked. However, I don't get that Venus ever supported life. Some ET crafts go to Venus, but they need a special protective shell, as the surface is very hostile. It's like it's angry, there. I don't see anyone ever being on Venus. No ruins or bases or anything."
