from the technically,-wasn't-Theia-a-meteorite? dept.

Planetologists at the University of Münster in Germany have determined when the Earth got its water. The inner solar system where the Earth formed is relatively dry, so Earth shouldn't have water. It turns out that water was delivered by the impact that caused the formation of the Moon.

Planetologists at the University of Münster (Germany) have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago. The Moon was formed when Earth was hit by a body about the size of Mars, also called Theia. Until now, scientists had assumed that Theia originated in the inner solar system near the Earth. However, researchers from Münster can now show that Theia comes from the outer solar system, and it delivered large quantities of water to Earth. The results are published in the current issue of Nature Astronomy.

This is in contrast to earlier theories of how and when Earth got its water which attribute it to being there at formation or delivered later by meteorites.

    7 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. [biblegateway.com]

    8 And God called the firmament Heaven. And the evening and the morning were the second day.

    9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.

    And then your imaginary sky daddy molested your 9 year old son. Where do you think the priests got it from?

    KJV blows monkey balls. How the fuck can you appreciate ancient mythology with piss-poor translations like that? The Message [biblegateway.com]:

    God spoke: “Sky! In the middle of the waters;
                    separate water from water!”
            God made sky.
            He separated the water under sky
                    from the water above sky.
            And there it was:
                    he named sky the Heavens;
            It was evening, it was morning—
            Day Two.

    God spoke: “Separate!
                    Water-beneath-Heaven, gather into one place;
            Land, appear!”
                    And there it was.
            God named the land Earth.
                    He named the pooled water Ocean.
            God saw that it was good.

    I also recommend reading the Gospels in MSG. You Christians might want to consider the teachings of that Jesus guy, but I understand why you aren't aware of the good news with your nose stuck in KJV. Trigger warning: Jesus is a socialist.
