Earth's Water Didn't Come From Outer Space

sciencehabit writes "Where did Earth's oceans come from? Astronomers have long contended that icy comets and asteroids delivered the water for them during an epoch of heavy bombardment that ended about 3.9 billion years ago. But a new study suggests that Earth supplied its own water, leaching it from the rocks that formed the planet. The finding may help explain why life on Earth appeared so early, and it may indicate that other rocky worlds are also awash in vast seas."

    So... is that your way of avoiding clicking on the link and realizing that you're wrong, by definition? Or is it that you've already had to admit it to yourself, so now you're mad at me?
