Venus was at one time thought to be the planet that was most like the Earth. It was often even referred to as Earth's sister planet. Venus is 95% the size of the Earth, has a density close to Earth's and is only about 30% closer to the Sun.  So there were many reasons to believe Venus might be just like the Earth only a little warmer. It has only been in the last 10 or so years that we have discovered that Venus is anything but Earth's twin. Venus is a blistering inferno with temperatures exceeding 880 degrees F and weather which rain sulfuric acid!
