I spotted this science story in the Los Angeles Times. I don’t suppose we think very much about water. Its just there. But some astronomers suspect that much of the water we drink has been around before the Earth was formed.
Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research.
That makes them older than the Earth, older than the solar system — even older than the sun itself.
In a study published Thursday in Science, researchers say the distinct chemical signature of the water on Earth and throughout the solar system could occur only if some of that water formed before the swirling disk of dust and gas gave birth to the planets, moons, comets and asteroids.
This primordial water makes up 30% to 50% of the water on Earth, the researchers estimate.
“It’s pretty amazing that a significant fraction of water on Earth predates the sun and the solar system,” said study leader Ilse Cleeves, an astronomer at the University of Michigan.
This finding suggests that water, a key ingredient of life, may be common in young planetary systems across the universe, Cleeves and her colleagues say.
I would think that water, in some form, would be rather common throughout the universe. It is made out of hydrogen and oxygen, two of the more common elements. There is more information about how the astronomers have come to their conclusions in the article.
I do not usually try to reconcile the text of the first chapters of Genesis with the findings of modern science. That is best left to those more learned in science and theology than I am. I am simply content to read Genesis to find out who created the universe and I turn to science to learn how He did it. Still, I am occasionally struck by how the writer of Genesis seems to have a better understanding of creation than any Bronze Age shepherd has any business having. Consider the very first verses.
In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from the darkness. 5 God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day.
The first thing God created was light. The earliest event in the universe we can have any knowledge of would be the Big Bang. If you have the right instruments you can still see the light of creation. But it is the second and third days that this story reminds me of.
6 And God said, “Let there be a vault between the waters to separate water from water.”7 So God made the vault and separated the water under the vault from the water above it. And it was so. 8 God called the vault “sky.” And there was evening, and there was morning—the second day.
9 And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. 10 God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good.
11 Then God said, “Let the land produce vegetation: seed-bearing plants and trees on the land that bear fruit with seed in it, according to their various kinds.” And it was so. 12 The land produced vegetation: plants bearing seed according to their kinds and trees bearing fruit with seed in it according to their kinds. And God saw that it was good. 13 And there was evening, and there was morning—the third day.
God created water before the dry land. Evidently water predates the planets. Now, plants are shown to be created before the Sun and Moon. This presents a problem since plants cannot survive without the Sun. But instead of plants, think the most primitive forms of life, perhaps bacteria, or even life simpler than bacteria. Some scientists believe that life may have arisen in space and traveled throughout the universe before landing on Earth. If this panspermia hypothesis is correct, then it is possible that life might also predate the formation of the solar system. There is no evidence in favor of this hypothesis. No actual life has been detected in interstellar space, though organic molecules, such as amino acids, have been.
But this is all speculation on my part and I really should leave this to wiser minds.
