Could a planet have liquid water without an atmosphere?

I once knew both how atmospheres formed on planets and how oceans of liquid water formed on planets, but I have forgotten that information. I know that both atmospheres and oceans of liquid water formed due to chemical reactions, but I used to know more of the details of what type of matters formed oceans and atmospheres. Since I no longer know the details, I no longer know whether or not it would be possible for planets to have oceans of liquid water without an atmosphere of oxygen and other elements that make up air. I no longer know if water and an atmosphere must necessarily go together.


For the purposes of my question, i'm asking if a planet could have liquid water without any intelligent life bringing the liquid water to the planet and without an atmosphere.

Without any intelligent life bringing liquid water to a planet, could a planet have large oceans of liquid water without an atmosphere? Please explain your answers.

Please post your sources that suggest that this is possible. Members, please allow the member to post his sources from his research. Thank you.

Evo, if I knew that it was possible for planets to have liquid water without an atmosphere, why would I be asking the question?!

Evo, my source on both how the oceans on Earth formed and how the atmosphere of Earth formed, was either one of many different popular science books or it was from Carl Sagan's Cosmos tv series. I'm thinking maybe I got such information from either Stephen Hawking's A Brief History of Time or one of Hawking's other books.

Here is a brief explanation of how the Earth's atmosphere formed:
When Earth formed 4.6 billion years ago from a hot mix of gases and solids, it had almost no atmosphere. The surface was molten. As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere. After about half a billion years, Earth’s surface cooled and solidified enough for water to collect on it.

Water was thought to be present in the material that formed the planet, was spewed into the atmosphere by volcanic activity, and condensed into oceans after the planet cooled. Early Earth's atmosphere did not have any oxygen, and oxygen appeared in the atmosphere only after life had appeared and evolved the ability to perform photosynthesis (http://www.scientificamerican.com/article/origin-of-oxygen-in-atmosphere/).
