It is true that putting all the objects in the asteroid belt together will "not" make them a big star, and not even a small star in the size of the moon, but the objects themselves are remains of a star, signs of a star.

It is the second sun that prevented Mars from having the size that is supposed to have.

The moon was originally the first planet next to the sun!

Gases from the dying second sun attracted to gas planets and increased their mass and gas volume.

The second sun, by the end of its life, failed to burn fuel and convert it to light; so where do you think the hot fuel will go? To the cold body! And that is exactly what happened, most of the remaining fuel, rust and dust, have gone to the cold bodies, Jupiter and Saturn, so their size and mass increased; Uranus and Neptune were not affected that much because they are very far away from the asteroid belt, the final orbit of the second sun.

QUOTE: "It was almost the perfect crime. Some perpetrator -- or perpetrators -- committed murder on a scale unequaled in the history of the world. They left few clues to their identity, and they buried all the evidence under layers and layers of earth. The case has gone unsolved for years -- 250 million years, that is."

At the end of its life, the second sun failed to convert gamma rays to light. These strong gamma rays have hit the earth and the other inner planets directly, interacted with gases inside the earth's internal layers, the gases expanded, the earth's crust opened up in some places. Rocks from the second sun have fallen from the sky and entered the earths' internal layers from the open areas. The rocks melted and released their metals. The released metal concentrated in the center of the earth, which is the center of mass, and started to form the inner core. The melted rocks are still releasing metal now, so the inner core of Earth is getting bigger.

Solid materials orbiting a dying star

Ice Asteroid on Mars, 60 km across, 2 km thick

200 million years ago the earth's gravity was very low, because the inner core was very small. If the dinosaurs weren't very large animals, their life on a low gravity Earth could have been impossible.

It is thought that dying stars do not produce solid materials, rocks and metal asteroids, but observations of dying stars elsewhere in space have shown rocks and metals orbiting dying stars. These solid materials are products of the dying stars themselves, and not of nearby destroyed planets, as assumed. Not all stars are the same. Some maybe destroying planets, but not all.

Some other chemical elements have combined together and created rocks that make up rocky mountains, and then fallen on Earth and the other inner planets. These rocks are the same as the rocks orbiting now in the asteroid belt. The earth had no rocky mountains 200 mya, but only sandstones.

Some rocks have created mountains, others have gone inside the earth's internal layers and melted there, and then reproduced to form lowlands (the seafloor).

As a result of the added materials, the earth has expanded. The Earth expanded once only, and not continuously expanding, as suggested by the Expanding Earth Theory.

The ocean waters cause continents to drift. There was no continental drift before the expansion of earth, 200 mya.

Ocean Tides cause continental drift

The ocean tides, the rise and fall of sea level, move a large volume of water from one place to another. This process is like applying alternating forces on an object continuously, making the object in an unstable state. The object here is the ocean crust, and the alternating force is the ocean water.

The hot magma inside the earth's interior moves in an opposite direction to the movement of the large volume of water. The movement of water and magma causes the seafloor to be recycled in one place, in an ocean trench, and reproduced in another place, from an ocean ridge. This leads the ocean floor to shrink in one place, and expand in another. So if there is no rise and fall of sea level (no movement of water), there will not be any magma movement, and therefore there will not be any tectonic activities at all.

It has been noticed that ocean tides trigger earthquakes at ocean ridges, when the tide at the ridges is low. There must be a large volume of water sitting on trenches somewhere else, and that forced magma to come out, causing earthquake, and also the seafloor to spread slightly, at the ridges, where the ocean tide is low. This phenomenon shows a direct relation between ocean tides and the tectonic activities.

Why is the continental (land) crust not destroyed and recycled like the oceanic crust, expanding in one place and shrinking in another, with trenches like in the ocean? Not because it is thicker, but simply because it is in a stable state. No alternating forces are applied on it.

Mars Expanded!!

Not just the Earth, the other inner planets have also expanded. The lowlands (blue) on the other planets, which are equivalent to the ocean floor on Earth, are added parts. All lowlands, in all planets, are younger in age than the highlands.

According to the crater counting technique, the surface of a planet with less craters must be younger than the surface on the same planet with more craters. Mars lowland is much smoother than the highland, with very few craters, which indicates that it is much younger than the highland. Mars expanded.

Frozen water on Mars: "More than 21 million km³ of ice have been detected at or near the surface of Mars, enough to cover the whole planet to a depth of 35 meters (115 ft)." (wikipedia.org)

Ancient ocean discovered on Mars!

Most of the frozen waters deposited on Mars, in the form of ice asteroids, have melted, and then evaporated to space, because of the thin atmosphere of the planet, but Earth preserved the received water. The water covered the whole planet Earth. Traces of this water can be found now in many places on Earth, but scientists assume that the traces are of ancient oceans.

There is no difference between the assumed ancient oceans on Earth and those that have supposedly existed on Mars in ancient times. The traces of water in these two planets are not of real oceans, but of a large volume of water that has fallen as ice from the sky, stayed temporary in some areas, and then shifted place gradually over thousands of years, but on Mars, it has evaporated to space. The thickness of the atmosphere of Mars is less than 1% of that of Earth, so it didn't help the planet to keep the received water.

Few Rocks: "there are few 250 million-year-old rocks left on Earth. Most have been recycled by our planet's tectonic activity" - (science.nasa.gov)

The absence of rocks is attributed to a theory that has NOT been proven to exist before 200 million years.

The few rocks in the quote above are very likely asteroids, or incorrectly dated rocks, but not remains of the supposed ancient rocky mountains.

Volcanism wasn't the only event to happen during the extinction, 200 mya, but other major events have also taken place in the same time: mountains were rising, the ocean floor was forming, and the earth was taking a completely different shape, so how to explain all of this happening simultaneously? There must be a one factor only that has caused this combination to happen together.
