Is their a planet in space with water on it?
Considering water is made with Oxygen and Hydrogen, the only planets that could have water on them would have to have plants. Humans haven't discovered many planets due to the difficulty. We are not advanced enough to know much of this. As space exploration goes on, people learn knew things about the Universe and planets. If humans ever did find a planet with wildlife on it, we'd probably land there, and manage to survive. Humans would most likely eventually colonize on other planets. However, the chances of planets in our solar system having wildlife on them is slim, and to find these, we'd need to travel very far from Earth, once again bringing my point that humans are not advanced enough.
