Is Venus had an atmosphere like Earth, how hot would it be?

According to some hypothesis, venus and earth used to have similar atmospheres but while the earth evolved in order to sustain human life, Venus is still composed of a lot of things that will be considered uncomfortable or deadly to human beings. Venus is known to have a hotter temperature.

This is the main reason why it has more water vapors as compared to bodies of water. The temperature in Venus is well beyond water’s boiling point. It will be true to say that the temperature will be very hot indeed. Some say that it will be impossible to revive this planet mainly because the same process will be done all over and over again because of its temperature.
