Complex life forms may have been on earth for billions of years
Humans are not the first complex life form to appear on this planet. The presumed aged of earth is only 4.6 billion years old, but there is growing evidence that our planet, and life on it – not just single-celled organisms – has been around much longer than experts have told us.
First, carbon-laced crystals have been found that are 300 million years older than the previously assumed “oldest life on earth” which date to 4.5 million years in age. While these crystals don’t necessarily prove that biological life existed, they do suggest chemical signs of life.
Then, there are the giant footprints that have been found in places like Sri Lanka that are dated to between 200 million and several billion years ago. There are also pictures of teeth, arms, ribs, and more that The Smithsonian, and many other institutions, have claimed don’t exist, but have been documented by other researchers. (True Legends)
Now researchers are saying that another form of complex life once existed on the earth but then disappeared, only later reappearing again.
A study conducted by scientists from the University of Washington (UW), suggests that more than a billion years before life really took hold on land, complex life developed in the earth’s oceans.
In a paper published Jan. 18 in the Proceedings of the National Academy of Sciences, lead author Michael Kipp, a UW doctoral student in Earth and space sciences, analyzed isotopic ratios of the element selenium in sedimentary rocks to measure the presence of oxygen in Earth’s atmosphere between 2 and 2.4 billion years ago.
Lead researcher, Eva Stüeken and Roger Buick, state in the paper,
“There is fossil evidence of complex cells that go back maybe 1 ¾ billion years,” said Buick. “But the oldest fossil is not necessarily the oldest one that ever lived — because the chances of getting preserved as a fossil are pretty low.
“This research shows that there was enough oxygen in the environment to have allowed complex cells to have evolved, and to have become ecologically important, before there was fossil evidence.” He added, “That doesn’t mean that they did — but they could have.”
Researchers used element selenium in sedimentary rocks as a tool to measure oxygen levels in the Earth’s atmosphere some 2 to 2.4 billion years ago.
Though it is not the first time the theory of increased oxygen has been proposed, the study sheds new light on how selenium had been changed by the presence of oxygen and affected the appearance and disappearance of complex life.
Buick explains that scientists previously thought that oxygen on Earth had a history of “none, then some, then a lot. But what it looks like now is, there was a period of a quarter of a billion years or so where oxygen came quite high, and then sunk back down again.”
The oxygen’s persistence over a long stretch of time is an important factor, Kipp stressed: “Whereas before and after maybe there were transient environments that could have occasionally supported these organisms, to get them to evolve and be a substantial part of the ecosystem, you need oxygen to persist for a long time.”
Stüeken said such an oxygen increase has been guessed at previously, but it was unclear how widespread it was. This research creates a clearer picture of what this oxygen “overshoot” looked like: “That it was moderately significant in the atmosphere and surface ocean — but not at all in the deep ocean.”
No one knows why oxygen levels soared and then crashed.
There is already evidence which suggests that exoplanet atmospheric density can change life on a planet, and we also know that the cabal has been playing with our atmosphere and weather using HAARP and other technologies which have been made relatively public; however, alterations to our magnetosphere could also induce great changes affecting life on our planet.
Has our planet been terraformed for life? Have other species deliberately modified our atmosphere, temperature, surface topography, and ecology to make this planet habitable? Does this account for an oxygen gap?
The term “terraforming” was invented by author Jack Williamson in his 1942 short story “Collision Orbit,” published in Astounding Science Fiction but maybe it isn’t fiction at all.
It is also possible that the same forces which seem provoked to ruin our atmosphere and life on earth today could have destroyed the planet in the far distant past. Dr. Brandenburg, a physicist well known in ufology circles claims that Mars was wiped out by an alien race which used nuclear bombs, and that the earth could be next
The creation and loss of life on this plant seems to have many secrets, which still urgently need to be revealed.
