Are Earth’s Oceans Made Of Extraterrestrial Material?

From Science Daily:

Contrary to preconceived notions, the atmosphere and the oceans were perhaps not formed from vapors emitted during intense volcanism at the dawning of our planet. Francis Albarède of the Laboratoire des Sciences de la Terre (CNRS / ENS Lyon / Université Claude Bernard) suggests that water was not part of the Earth’s initial inventory but stems from the turbulence caused in the outer Solar System by giant planets. Ice-covered asteroids thus reached the Earth around one hundred million years after the birth of the planets.

The Earth’s water could therefore be extraterrestrial, have arrived late in its accretion history, and its presence could have facilitated plate tectonics even before life appeared. The conclusions of the study carried out by Albarède feature in an article published on the 29 October 2009 in the journal Nature.

Space agencies have got the message: wherever there is life there has to be water. Around 4.5 billion years ago, the Earth was bequeathed with sufficient water for oceans to form and for life to find favorable niches in the seas and on the continents resulting from plate tectonics. In comparison, the Moon and Mercury are dry, mortally cold deserts, Mars dried up very quickly and the surface of Venus is a burning inferno…

    If the Earth's water, and therefore subsequent life, are from another place in the Solar System, how come it doesn't say anything about it in The Bible? Didn't think about that, did ya, Mr. Smarty Pants Science Guy?

      Bible???..wtf…is this the 21 Century???…science is always evolving…

      • tonyviner

        The Bible is always evolving too, just not the people that read it.

          The bible has had smaller changes made to it, to fit in with popular science. If you read your bible it is very illogical. The bible was written a long time ago, with the advances in science there would not be any information on this in it.

    The whole earth is made of extraterrestrial materials, logic fail.
