Mars, Because they found water like flow patterns like found on Earth, Water is an essential ingredient for life.
Water is the only item found on earth in three different phases of matter at standard pressure.
Earth is the only planet that has life on it because it is just the right temperature to grow plants, and as you know,that plants give us oxygen to breathe in which is why me and you are alive right now!!If you ask someone why is there no life in Mercury, he/she will say that mercury is way too close to the sun and is too hot to grow any plants. Therefore Earth gets the right amount of heat to grow plants in.A Extra FactEarth is the only planet we've taken a really close look at. For all we know, there are half a dozen other planets and moons in our system supporting life at this very moment.
