Also, all planets in our solar system but earth have no water, which automatically disqualifies them. Mercury - Too close to the sun, blisteringly hot due to intense heat of the sun. Very, very hot. Venus - Hotter than mercury, but further away. read more

Additionally, another theory I have come across is that in our solar system, it is just a matter of time before other planets become uninhabitable or inhabitable. Just like Mars was once habitable and then became uninhabitable, Earth shares the same fate, and so will Venus too. Mars, Earth and Venus possibly share the same lifespan. read more

Also, our planet has enough mass to hold an atmosphere (Mars or Mercury) and a low enough pressure and heat to not instantly cook life(Venus). Keep in mind that just because we haven't found any other life in the solar system doesn't mean it isn't their. read more
