The first 4 planets in our solar system are rocky. The next 4 are gassy. The latter also shepherd rings of debris while the former do not. Why exactly so is a mystery.
If we examine the perfect solar system model, we would have a dense core which becomes our sun, and layers of less dense “waters” around it.
At a certain time, the sun acquired critical mass and ignited. The first things to be ejected from our star formed the Oort cloud, the farthest reaches of our system. Then gas was expelled, forming the giant planets, Jupiter to Neptune. Finally, our Earth and its sisters coalesced. The reason we’re not gas giants is simply there was not enough gas around our orbit(s).
Gassy exteriors shielded the giant outer planets from fully accumulating the Kuiper belt and asteroid belt being seated in a less steep gravity well. While the Oort cloud which has no (known) shepherd, is wild and chaotic, sending comets back towards the sun at its gravitational will.
The origin of moons is next. Mars’ moon is very close and small. Earth’s moon is larger and further out, while Venus has a captive asteroid-comet. The outer giants have many moons. The formation of moons and rings is fractal-gravitationally more probable than being without them. The reason there are fewer moons inward the solar system is that there are steeper gravity wells.
The reason Earth’s moon is further out than Mars’ is because while Mars sits in a dimple gravity well, it and its moon formed close, temporally while Earth’s did not. Venus had no such luxury. Its moon never formed. The only reason must be the gravity of the Sun working against planetary mass.
Venus, having no moon became torrid, Mars, rubbed dry and airless by Phobos, while on Earth, a suitably thinner atmosphere prevailed, shepherded by our distant moon.
More later…
The core of the Earth is a giant magnet. A pole shift such as the Bible indicates, requires the core to slow down first, then, volcanic activity ensues over it because of the reduction in friction. Then the crust of the planet, perhaps some layers below slip over the core. It is uncertain why the core should resume spinning on its own other than that the Sun should expand and cool drastically, thus having some proximity / intensity effect.
