Habitable zones

Earth is probably the only planet that can sustain life and one of these reasons lies with the goldilocks zones. The goldilocks zone is not too hot and not too cold and just moderate enough temperature to sustain life. This is also why it is different to other planets which has free abundance of oxygen, liquid water and moderate temperature. Any water on Venus would vaporize making it near to impossible to sustain life there. Also mars is far too freezing and life would freeze. At the moment Earth has the only intelligent life known to mankind.

Life, as we humans know it,
