SoulFood (12) How the sea got here

      In a first for space history; a spacecraft called Rosetta, was recently maneuvered alongside a speeding comet to begin mapping its surface in detail. The spacecraft fired its thrusters for six and a half minutes to finally catch up with comet 67P/Churyumov-Gerasimenko. "We're at the comet!" said Sylvain Lodiot of the European Space Agency (Esa) operations center in Germany.
       "After 10 years, five months and four days travelling towards our destination, looping around the Sun five times and clocking up 6.4 billion km, we are delighted to announce finally 'we are here'," said Jean-Jacques Dordain, director general of Esa.
       Launched on board an Ariane rocket in March 2004, Rosetta has taken a long route around our Solar System to catch up with comet 67P. In a series of fly-pasts, the probe used the gravity of the Earth and Mars to increase its speed during the 6 billion km chase. Many hope this visit to the comet will verify the current theory about comets and our sea. That is just one of its many tasks.
       Wait, there’s a connection between comets and the blue waves of earth? Some say there is.
       How much water is in the ocean? - National Ocean Service - About 96 percent of Earth's water is in the ocean. That's enough water to fill about 343,670,000,000,000,000,000 gallon-sized milk cartons... 343 billion BILLION gallons.
       How did that much water get here? The Bible says God made the sea. Some scientists accept that as one possible answer to a great mystery.  Others however are banking on another explanation. Perhaps the most popular theory says that, shortly after the Earth formed and cooled, millions of asteroids and comets, saturated in water, slammed into the planet, releasing their payloads to form Earth's oceans. This idea was first put forward at the University of Hawaii.
      There are some mathematical problems with this explanation. For example: if we took Haley's Comet as one of average size and bearing the amount of water that it does, we would need 150 million of such sized comets to bring us our sea. Now we don't just mean fly past us like most comets do. We are talking about 150 million collisions.
      How many years would that take at the present rate of comets colliding with earth?  First we ask when was the last one? 13 thousand years ago has been suggested as the reason for the sudden destruction of the dinosaurs. Let's say then that we are due for our next one soon. 150 million times 13 thousand years means the first impact should have been 195 000,000,000 years ago. That is 195 billion years ago.  Oh oh. That is 13 times older than science estimates the age of our earth.  In other words if the sea came riding here on comets the ocean would be very much smaller than it is. That is where a few desperate scientists resort to faith! They just believe – because it fits their theory – that the rate of collisions and the amounts of water were much higher in the early years.
      Now if we have to add faith into the discussion, we may as well include a category labeled: “Intelligent Design.”  So could God have made the sea? That's no worse an explanation than the best that believers in chance plus time have to offer. The origin of the sea remains a mystery and it calls for faith one way or another.
       “And God said, “Let there be a vault between the waters to separate water from water.” So God made the vault and separated the water under the vault from the water above it. And it was so. God called the vault “sky.” And God said, “Let the water under the sky be gathered to one place, and let dry ground appear.” And it was so. God called the dry ground “land,” and the gathered waters he called “seas.” And God saw that it was good.”

       Too simple an explanation? It would be simple for an all-powerful, all-knowing Being, Who can best be thought of, in scientific terms, as the “first cause.”
