Texas Scientists Discover the Source of Earth's Primordial Oceans

Evolutionist researchers at the Southwest Research Institutes may have discovered a solution for a scientific paradox related to the origins of life on Earth.

The study, published in Earth and Planetary Science Letters journal, deals with the so called ‘faint young Sun paradox’ – an apparent contradiction between findings suggesting the presence of liquid water on Earth during the planet’s early history and the expectations that the Sun’s output during that time period would be 70 percent as intense as it is today.

Despite the fact that the estimated amounts of solar power wouldn’t be enough to sustain liquid water on the planet, evidence like ancient zircon crystals in sedimentary rocks suggest that somehow Earth did in fact have liquid oceans back then.

The scientists believe that the answer to this paradox lies with primordial asteroids that bombarded Earth during the first billion years of its history.

“The early impacts caused temporary, localized destruction and hostile conditions for life. But at the same time, they had a long-term beneficial effect in stabilizing surface temperatures and delivering key elements for life as we know it,” Dr. Simone Marchi, a senior research scientist at Southwest Research Institute’s Planetary Science Directorate, said.

According to the study, this phenomenon essentially resulted in a massive atmospheric greenhouse effect produced by either carbon dioxide or methane (or even a combination of both). The model created by Marchi’s team suggests that asteroid impacts resulted in large volumes of rock melting and creating temporary lakes of lava which could have released large quantities of gases into the atmosphere.

“This early heavy bombardment could have been responsible for the large greenhouse effect needed to maintain warmer conditions, which may have been conducive to the early start for life on Earth. The bombardment also delivered large quantities of sulfur, one of the most important elements for life,” Marchi added.

    I dont think thats how it happened.
    I think that Earth and other proto-planets were glowing and orbiting the young Sun in the accretion disk, wich contained high level of hydrogen, oxygen and water ice crystals, I think what happened is that as it went through this “soup” and the surface was glowing the gases and the water ice simply condansated onto the surface creating the oceans.

      And your evidence for this is what ?

      • Lone Ranger

        Whats their evidence?
        If you look at all the models they have presented in the past decades mine sounds as the most plausible, in my humble opinion, also Im not a 100% sure of it, how could I be, but it sounds more basedthan comets and asteroids with green house gases.

    Oceans are Gods tears!……..that’s why its salty!

    • Lone Ranger

      That was actually beautiful.

    That’s old news and the most probable scenario. The temperature generated during gravitational collapse of a planet excludes the formation of water molecules so most likely the Hydrogen and Oxygen would form other acids and radicals (unlike in a mid sequence star such as our sun which primarily was made of hydrogen (then to helium to oxygen to carbon then death). The original Earth was much smaller and consisted mostly of heavier elements. The current amount of water was produced through the dissociation of mostly sulfuric acid created in the beginning, but only under the conditions of a cold surface to allow convective currents in the original mantle which was probably created by large impacts of ice meteorites that were far more abundant 5 billion years ago than now (age of universe is 13-14 billion)
