Venus and Earth used to look like 'twin' planets. What happened?

PO1 William "Chip" Nagel Those planets — Earth, Mars, and Venus — look very different from each other today. Earth is a temperate, blue-green marble transformed by living things. Meanwhile, its siblings have migrated to two extremes: Mars is a dry, cold, dusty planet with a paper-thin atmosphere, and Venus is the hottest planet in the solar system, covered in a thick atmosphere that quickly destroys even nonliving visitors from Earth.

According to my best friend (may he rest in peace) When Elvis "died" he went to Venus along with the other Aliens and set up camp. So the paparazzi couldn't see them, they filled the atmosphere with cigar smoke. He said: "That' just science."
