What is the “Last Chance Lake? It is  a shallow, extremely salty pool of water with an unusual chemistry. The lake has phosphate concentrations 1,000 times higher than the ocean, making it a modern analog

Evolution believing scientist say that it has been around 4 billion years ago. ”Phosphate is an essential ingredient to make nucleotides — the building blocks of DNA and RNA — and other life-forming compounds, such as lipids. Although phosphate is bound up in every living being, the element by itself is scarce in nature.”

"Someone coined the phrase 'the phosphate problem' for the origin of life, which is that you need a lot of phosphate for these reactions," Sebastian Haas, a postdoctoral researcher in the Department of Earth and Space Sciences at the University of Washington, told Live Science. "The second part of the problem is that phosphate is usually low in the environment, and the only real exception we know are these kinds of lakes."

 Last Chance Lake is one of several so-called "soda lakes" — lakes that have high levels of dissolved sodium and carbonate. That makes them similar to bowls of water containing large amounts of dissolved baking soda. This chemical makeup enables these lakes to have high concentrations of phosphate.”

So some evolution believing scientist say that it may have given life on Earth.

Life currently has a sample size of just one. Without an alien or two to expand the boundaries of biology, Earth’s  evolutionary history set the limits on what we could find  in the cosmos. .

 However,  giants, impossible planets and other impossible planets   and red giants cannot are not the source to find live.  

 But now it seems that a great number of exoplanets will not do, .It seems we are alone in the universe.  

Planets are also need Phosporus  

Phosphorus (P) is one of our planet’s general chemical elements. Without it we would not have RNA , DNA and our ATP, and thus we would not have life.

Life on Earth may have begun with a flash of  lightning.

According to evolutionists, the answer to how we got the phosphorus it needed to make the first DNA and RNA molecules might be in the sky.  A new study, lead by Benjamin Hess, a graduate student at Yale University's Department of Earth and Planetary Sciences said that "Lightning strikes may have therefore played a role in providing phosphoros . …we show for the first time that lightning strikes were likely a significant source of reactive phosphorus on Earth around the time that life formed 3.5 billion to 4.5 billion years ago,"

Phosphorus (P) is one of our planet’s general chemical elements. Without it we would not have RNA , DNA and our ATP, and thus we would not have life.

Just recently, we heard that life could start on Venus, which was  later proved to be false.

Early 'Soda Lakes' Have Provided Missing Ingredient Key to the Origin of Life

Lakes that thrived in dry locations on early Earth likely played a key role in supplying phosphorus, researchers wrote in a new study published Dec. 30 in the journal Proceedings of the National Academy of Sciences.

Phosphorus is crucial to life, Without it we not have it.

Phosphorus is crucial to life as we know it. The mineral helps form the backbone of DNA and RNA molecules; anchors lipids, or fats, that separate cells from the environment around them; and helps provide life energy, serving as the main component in molecules such as adenosine triphosphate, or ATP.

The finding explains how this scarce mineral became abundant in Earth's primordial soup. Put more plainly, it helps scientists understand how life likely arose. "For 50 years, what's called 'the phosphate problem,' has plagued studies on the origin of life," study co-researcher Jonathan Tone , a research assistant professor of Earth and space sciences at the University of Washington, said in a statement.

The building blocks of proteins, DNA and RNA — in essence, the key ingredients of life, the researchers said.

As a result, some of the phosphate is freely available in the water, according to experiments done by Toner and Catling.

"The extremely high phosphate levels in these lakes and ponds would have driven reactions that put phosphorus into the molecular building blocks of RNA, proteins and fats, all of which were needed to get life going," Catling said in the statement.

About 4 billion years ago , early Earth's carbon dioxide-rich air would have helped create such lakes with high phosphorus levels, the researchers said.


Now,who made this transition?
.
This study complements another paper the two researchers published in 2019, which shows that soda lakes can also supply ample cyanide, a chemical that is deadly to humans but not to primitive microbes. Cyanide could have supported the formation of amino acids and nucleotides, the building blocks of proteins, DNA and RNA — in essence, the key ingredients of life, the researchers said.

Biodiversity on Some Alien Planets May Dwarf That of Earth

It seems that we don't have optimum ocean-circulation patterns on Earth.

"Earth's dazzling biodiversity may not be so remarkable in the cosmic scheme of things, a new study suggests.

Alien planets with more favourable ocean-circulation patterns might support life in even greater abundance and variety than our own world does, the study determined.

"Life in Earth's oceans depends on upwelling (upward flow), which returns nutrients from the dark depths of the ocean to the sunlit portions of the ocean where photosynthetic life lives," study leader Stephanie Olson, of the University of Chicago, said in a statement."

However, we do not know the state of affair on exoplanets. We do not know, for instance, if a planet's contains phosphorus, without which which we would not have RNA , DNA, and our ATP, and thus we would not have life. And also if it contains all ingredients that make life necessary.

Alien Life Could be Hiding Out in Only Half The Places We Thought It Would

"Where is complex alien life hanging out in the universe? Likely not on planets stewing in toxic gases, according to a new study that dramatically reduces the number of worlds where scientists will have the best luck finding ET.

In the past, researchers defined the ‘habitable zone’ based on the distance between the planet and its star; planets that, like Earth, orbit at just the right distance to accommodate temperatures in which liquid water could exist on the planetary surface would be considered ‘habitable.’ But while this definition works for basic, single-celled microbes, it doesn't work for complex creatures, such as animals ranging from sponges to humans, the researchers said.

Under the new parameters, some stars have no safe-for-life zone; that includes Proxima Centauri and TRAPPIST-1, two of the sun's closest neighbors. That's because planets around these suns likely have high concentrations of carbon monoxide, the researchers said. Carbon monoxide can bind to hemoglobin in animal blood, and even small amounts of it can be deadly."

We have found 4,000 exoplanets but with (almost) no right for live. there’s not a single one we might call home.

Where did we get our phosphorus, that is vital for our DNA, RNA our ATP.

Our home planet has all these ingredients.

“The exoplanet, named K2-288Bb, could either be a rocky world like Earth or a gas-rich planet like Neptune.

The new world lies in a stellar system called K2-288, which includes two dim, cool M-type stars that are roughly 8.2 billion kilometers apart — about six times the distance between Saturn and the our Sun.

The brighter star of the pair is estimated to be half as large and massive as Earth's sun, while its dimmer companion is about one-third the sun's mass and size. This world lies 226 light-years from Earth, in the constellation Taurus K2-288Bb orbits this smaller and dimmer star every 31.3 days.

It resides within its host star's habitable zone, which means the planet may have liquid water on its surface. “

However, liquid water is not the only way way to look for life in the universe. One of the things that we should look for is Phosphorus, that is a chemical element with the symbol P.

Where Did We Get Our Phosphorus?

Phosphorus (P) is one of our planet’s general chemical elements. Without it we would not have RNA , DNA and our ATP, and thus we would not have life.

“’Phosphorus is one of the key elements in biology.’ says Matthew Pasek, an astrobiologist and geochemist at the University of South Florida.”

Now, Pasek, is on a search for who we got our phosphorus in the beginning. “Unlike the other elements essential for life, phosphorus is mainly found in solid form, whereas the likes of hydrogen, oxygen and nitrogen are often found as a gas.“ [Studying phosphorus] keeps us grounded in actual hard rock samples. Unlike the others, there is no obvious gas form, so has to come from rock sources,” Pasek says.

Meteorites also contain phosphorus. In Pasek’s thinking, published in the journal Icarus, “found that most phosphorus should be in a solid form everywhere in the Solar System, out to about Saturn.”

Mikhail Zolotov, thinks that Pasek’s work ok, but “it is contentious that gas movement toward the Sun, which was not modeled in the paper, could be faster than the diffusion of gas away from the Sun.”
