That depends on what you mean by life. If you mean life as we know it, the best bet is Mars, as it’s the most Earth-like of the other planets. But even the Earth is home to so-called extremophiles – organisms that can cope with extraordinary temperatures or radiation – so we shouldn’t be surprised if life exists elsewhere in the Solar System.

Any place with Hydrogen and Gravity...
Need I say more...
Want to know how the Earth has Water..... Look to the Stars... Our Own Star Actually Evaperates Hydrogen with helium, Hydrogen does not competely Turn into Helium, Some of it escapes and is sent out into space...
Thus, any planet with Gravity can attact Thus Hydrogen... Thus, The Water Crystals on the Moon our Mars is Not water, it is Hydrogen, that has been captured because of
Gravity...
This is How water Formed on the Earth, It was Close enough and not to far away to Attact most of the Hydrogen.... The Earths Watery surface was not water in the Begining but Hydrogen.... The Underwater Eruptions created Sulfer and Other Molecules that Created algae on the Rocks, This Algea Created Oxygen Molecules and Eventually Mixed complelty with Hydogen to Create Water..... Then The Water Was Still Evoporating Over the Years and Created the Poisonous Oxygen Layer that Sustains The Earths Atmosthere..... How do you Fix the Ozone Layer? By Releasing Trillions of Tones of Poisonous Oxygen into the Upper Atmoshere, Simple..
How do you Teraform a planet... By Manipulation of Atomic particles into other particles that Represent Hyrogen and Oxygen... It can be Done too... Just Manipulate the Stucture of Lets say the Dust particles on mars and Turn them into the Structure of Oxygen particles,.... Quantom Machanics....
