"There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Ea..." — Bill Nye

There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.
