Probably not Venus:The garden of Eden was on Mars or Venus i'd guess Venus due to biblical facts
Venus is very different from the Earth. It has no oceans and is surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor. Its clouds are composed of sulfuric acid droplets. At the surface, the atmospheric pressure is 92 times that of the Earth's at sea-level.
Venus is scorched with a surface temperature of about 482? C (900? F). This high temperature is primarily due to a runaway greenhouse effect caused by the heavy atmosphere of carbon dioxide. Sunlight passes through the atmosphere to heat the surface of the planet. Heat is radiated out, but is trapped by the dense atmosphere and not allowed to escape into space.
Here is my theory on things, I believe that not ever human is from earth. The garden of Eden was on Mars or Venus i'd guess Venus due to biblical facts, so I believe that most of use are aliens. This would explain some of the difference in ideas of ppl. But, I think do to breeding alot of what we would see as alien feature have been breed out, and some breed in.
