The problem is that you really don't know what you are talking about. A Velikovsky fan, I suspect.

Learn some science; then get back to us.

"God said it, I believe it, and that SETTLES it" is, I remember, a famous Teaxas bumper sticker. You are a brain-washed, orthodox believer, in I-S....fine. But like all true believers you disparage other viewpoints, sounds like a holier-than-thou liberal to this conservative... And you can't come up with a plausible explanation for the existence of the earth's oceans so long ago...who is the true scientist here?

RUSH LIMBAUGH : "FACTS are stubborn things". Fact : there are now some 384,000,000 cubic miles of H2O on the earth, covering 70% of its surface. As per fossil mushroom-shaped beach-rocks in australia we know the ocean was already in place 3.9 billion years ago. You claim to know all things, good, please explain to the class how all this water arrived onto the earth's surface so quickly after the earth's formation...

Cecilia Payne-Gaposchkin: Astronomer And Astrophysicist
1900-1980
by Owen Gingerich
Harvard Smithsonian Center for Astrophysics
http://www.harvardsquarelibrary.org/unitarians/payne2.html

In a short chapter entitled “The Relative Abundance of the Elements” there is a ticking time bomb. This is the extremely high abundance of hydrogen and helium that had come out under certain assumptions in the analysis. Although we know today that this high abundance is real, at the time it produced an apparent anomaly with respect to the assumed homogeneity of the solar system. After all, when the earth is taken as a whole, it must be predominately iron in order to account for its high mean density, and this is supported by the fact that meteorites are largely iron and by the appearance of the solar spectrum itself, which shows more lines of iron than any other element. The very important principle of uniformity of nature seemed at stake. As Cecilia herself argued in her thesis, “If . . . the earth originated from the surface layers of the sun, the percentage composition of the whole earth should resemble the composition of the solar (and therefore of a typical stellar) atmosphere. . . . Considering the possibility of atomic segregation both in the earth and in the star, it appears likely that the earth’s crust is representative of the stellar atmosphere.”21 So in her final table of abundances, she omitted hydrogen and helium.

The Neon Sun: New Study Appears to Solve Mystery
by Ker Than
27 July 2005
The Sun likely contains nearly three times more neon than previously thought, according to a new study. The finding, if shown to be accurate, solves a theoretical problem regarding how stars in general work... The model was put into question, however, when their value for the neon abundance in the Sun differed from those calculated using other techniques... Drake said the disagreement about the concentration of neon may have been due to problems with both the solar wind technique and the X-ray method... Drake and his colleague Paola Testa from the Massachusetts Institute of Technology got around these problems by measuring the neon abundance of 21 nearby Sun-like stars using NASA's Chandra X-ray Observatory... nearby stars contained three times more neon than was calculated for the Sun... Drake said the same technique could be used on our own Sun, if not for one problem: the detectors on Chandra's instruments would fry because of the heat.
IOW, the model is upheld, despite contradiction by the data. :')

Thermodynamic Law Party
The Thermodynamic Law Party Stand On Radioactivity
For too long the hoax of radioactivity has been perpetrated on the American people. Money that has been spent on so-called nuclear energy and nuclear weapons -- things that are in fact pseudoscientific mumbo-jumbo -- has actually been embezzled by corrupt government officials. The Thermodynamic Law Party will seek to expose these acts of malfeasance and to bring the truth to the American public about the non-existence of radioactivity, and the many lies that have been derived from it and other anti-Thermodynamic falsehoods. These include: the Earth's spontaneous internal "radioactive" sources of heat; an age of the Earth that is more than two orders of magnitude too large based on "radiometric dating"; the theories of evolution of species through transmutation, for which there was not enough time, and spontaneous generation of life from primordial ooze, which is in violation of the Laws of Thermodynamics; the silly idea that harmful microbial organisms can be rid from our food by exposure to "radioactive" elements; and the unwarranted fear of non-existent "radon gas". Since the Thermodynamic Law Party is grass-roots and independent of the political establishment, we will be able to work against the forces that are trying to spread these Entropic lies.

U of M researcher simulate characteristics of planetary cores
EurekAlert!
The researchers calculated what would happen at temperatures and pressures likely near the cores of the two exoplanets, Jupiter and Saturn, where temperatures run close to 18,000 F and pressures 10 million bars (a bar is essentially atmospheric pressure at sea level). They found that even post-perovskite could not withstand such conditions, and its crystals would dissociate into two new forms. Focusing on one of those crystals, the researchers discovered that they would behave almost like metals. That is, electrons in the crystals would be very mobile and carry electric current. This would have the effect of supporting the planet's magnetic field (if it has one) and inhibiting reversals of the field. The increased electrical activity would also help transport energy out of the core and toward the planet surface. This could result in more severe activities such as quakes and volcanoes on the surface. The effect would be much stronger in Dense-Saturn than in Super-Earth.

Solar System Formation Deduced from Observations of Matter

Authors: J. Marvin Herndon

Aspects of our Solar System's formation are deduced from observations of the chemical nature of matter. Massive cores are indicative of terrestrial-planet-composition-similarity to enstatite chondrite meteorites, whose highly-reduced state of oxidation may be thermodynamically stable in solar matter only at elevated temperatures and pressures. Consistent with the formation of Earth as envisioned by Arnold Eucken, thermodynamic considerations lead to the deduction that the terrestrial planets formed by liquid-condensation, raining out from the central regions of hot, gaseous protoplanets. The mass of protoplanetary-Earth, estimated to be 275-305mE, is similar to the mass of Jupiter, 318mE. Solar primordial gases and volatile elements were separated from the terrestrial planets early after planet formation, presumably during some super-luminous solar event, perhaps even before Mercury had completely formed. The pre-super-luminosity-terrestrial-planet mass distribution appears to be more consistent with observations of the close-in gas-giants of other planetary systems than the present-day-terrestrial-planet mass distribution. Although primarily formed by raining out from the centers of hot, gaseous protoplanets, evidence for the Earth and, by inference for the other terrestrial planets, suggests some outer, minor, secondary accretion of oxidized matter in the grain-growth accumulation way envisioned by George W. Wetherill. By contrast, the so-called "standard model" for our Solar System's formation has flawed conceptual underpinnings and would lead to the contradiction of terrestrial planets having insufficiently massive cores.

The Giant Crystal At The Heart Of The Earth
by William R. Corliss
Science Frontiers Online
No. 93: May-Jun 1994
Geophysicists have been forced to consider this possibility because of two anomalies:
1. Seismic waves from earthquakes pass through the earth's core faster when they travel parallel to the earth's axis than when they travel in the plane of the equator. The transit time difference is 2-4 seconds. Apparently, the earth's core is not perfectly spherical or its properties are different in different directions.

2. The natural vibration or "ringing" frequencies of the earth are "split," that is, instead of a series of single "tones" we detect a series of closely paired frequencies. This is symptomatic of a core that is anisotropic; that is, its properties are different in different directions.
J. Tromp, of Harvard, may have de-anomalized both sets of observations with a single theory:

"For the shape of the core alone to explain the observations, he says, the shape of the inner core would have to be very unrealistic. Instead, he claims that the inner core behaves like a giant asymmetric crystal, aligned with the Earth's axis so that seismic waves travel faster in that direction. Tromp's analysis fits neatly with suggestions that the inner core is made of a high-pressure phase of iron in which the atoms are close-packed in hexagons, because such a 'sigma' phase is anisotropic."

But, asks Tromp, how and why did the core material assume this crystalline character?

(Hecht, Jeff; "The Giant Crystal at the Heart of the Earth," New Scientist, p. 17, January 22, 1994.)

Comment. How does this big iron crystal jibe with the dynamo theory of the earth's magnetic field? Could Tromp's "giant asymmetric crystal" produce a permanent magnetic field, thereby forcing the supposed dynamo to play second magnetic fiddle?
