How could a planet with an atmosphere 5 times thicker than Earth even support life?

I was thinking about this. If an atmosphere had 5 times the thickness of Earth it would be comparable to water. A 20 mph gust would be like a 100 mph gust etc. Essentially no hope of buildings or trees or grass or anything really.

    Life would have evolved differently than it has here on earth. Just because earthlings couldn't survive in that kind of atmosphere doesn't have anything to do with what have evolved elsewhere.

    Where did you get that idea? Are you confusing thickness with density?

    Life evolves and adapts to the conditions of the environment.  On Planet Earth fish, tube worms have been found on the ocean floor so there is no reason to suppose that life couldn't survive on a planet whose atmosphere is 5 times thicker than ours.

    Maybe you should be asking biologists, not astronomers. Biologists are the people who specialize in life and would be the best people to consult about survival in extreme conditions, whether those conditions be on Earth or some fanciful "planet".
