Inhabitable
The Earth is more inhabitable than Mercury for several reasons. First of all, the distance the Earth has from the sun causes the earth's temperature to be just right compared to Mercury on which temperatures range from −183 °C to 427 °C. Also, the atmospheric conditions at Earth protect the life forms living there from harmful rays from the sun. Mercury does not have a substantial atmosphere.
