paleontologists, it's sometimes called the 'Great Dying.' Roughly a quarter of a
billion years ago, 90-95 percent of all life on Earth died out. It took 30
million years for the planet to recover. What happened? Most people are familiar
with the extinction event 65 million years ago that wiped out the dinosaurs. But
the Great Dying was much more devastating. It left almost nothing alive... Earth
scientists Sarda Sahney and Michael J Benton call it 'the most devastating
ecological event of all time."
It is mentioned in the quote above that 90-95% of life on the earth died out. It took the earth about 30 million years to recover. This type of life extinction adds evidence that shows that a completely abnormal event has taken place on Earth around that time, and lasted for a very, very long time. The cause must have been present all of this time.
Following this event is the formation of sea floor, rise of rocky mountains, and continental drift. Theorists, however, do not see any relationship between these events; even though they happened at exactly the same time, and on the same planet!
"The Earth was engulfed in widespread volcanism at the time of the extinction."
suggested many possible causes for the Great Dying: severe volcanism, a nearby
supernova, environmental changes wrought by the formation of a super-continent,
the devastating impact of a large asteroid --
or some combination of these.
Proving which theory is correct has been difficult."
It is written in the quote above that the cause could be a combination of these. Now if a "combination" is considered, this combination cannot be separate and isolated cases, all of them happening simultaneously in the same time, but a kind of one event triggering another, or one factor causing all of these events to happen together. Later in this section we will see a sign pointing to space as the source of this "combination."
Another assumed cause: "Lava flow 250 million years ago
likely killed most of Earth's life --A massive flow of molten rock, bubbling to
the surface and spreading more than a mile deep over an area half the size of
Australia, may have killed up to 90 percent of all animal species on Earth some
250 million years ago, a study suggests. The study shows that the flood of
molten rock that created what is known as the Siberian Traps in Russia was
almost twice as big as previously believed and could have continued for
thousands of years, changing the climate of the entire planet."
NASA has sent a team to sites in Hungary, Japan and China to study supposed causes of the Great Dying. There are rocks, originally fallen from space, in these countries with sizes of 6 to 12 km across, as big or bigger than Mt. Everest. The rocks still exist and have been exposed.
A sign pointing to space as a cause of the extinction:
Permian-Triassic rocks, Becker's team found soccer ball-shaped molecules called
'fullerenes' (or 'buckyballs') with traces of helium and argon gas trapped
inside. The fullerenes held an unusual number of 3He and 36Ar atoms
-- isotopes that are more common in space than on Earth."
From the same article at the link above; some have suggested that the fallen rocks caused the
extinction, but others believe that life has been already wiped out when the rocks have
arrived. The team leader said: "If life suddenly has all
these different things happen to it," Becker says, "and then you slam it with a
rock the size of Mt. Everest -- boy! That's just really bad luck."
What can be seen in the quotes above is "not" only the isotopes that are more common in space than on Earth, but also the rocks that contain these isotopes have actually fallen down from space. These rocks are exactly identical to the rocks that make up rocky mountains. And after knowing this, you don't need a magic formula to figure out that the rocks that make up rocky mountains have actually come from space, at the time of the extinction.
Identical rocks (at least in shape) are those that are found on the surface of Mars. And if the distribution of these rocks on the surface of Mars is more than any other planet, then the space object that distributed the rocks must have been near Mars. Now we are not trying to assume the impossible, but only using the common sense to see what has actually happened, and when it happened.
