He states that it has similar features to Earth such as valleys, mountains, and craters. While this may be too, Venus has come a long way in that it is no longer able to sustain life. Even if it previously was similar to Earth, that means that it has gotten worse over time, which says that from here on, it will continue to grow worse.
