there is no definitive evidence or confirmation of any planet other than Earth having trees. Trees, as we know them on Earth, are complex organisms that require specific conditions to thrive, including a suitable atmosphere, water, and a hospitable climate. While there are ongoing scientific investigations and missions exploring the possibility of life and habitable conditions on other planets and moons within our solar system and beyond, no conclusive evidence of trees or similar plant life has been discovered thus far.
It's worth noting that our understanding of the universe is constantly evolving, and future discoveries may change our knowledge regarding the existence of trees or similar forms of life on other celestial bodies.
