Currently, no planet other than Earth is known to support life. While scientists continue to search for signs of life on other planets and moons, Earth remains the only confirmed abode of life in our solar system.
While Mars is often cited as a potential candidate for supporting life, it's important to remember that even Mars lacks the essential conditions for life as we know it, such as liquid water on the surface and a substantial atmosphere.
However, some moons, like Europa (Jupiter's moon) and Enceladus (Saturn's moon), show promising signs of harboring life. These moons possess subsurface oceans that could potentially host microbial life.
In conclusion, while the search for extraterrestrial life continues, Earth remains the only known planet that supports life.
