Researches have found sugar molecules in a cosmic cloud nearly  27light i yeas from us, The ones who believe in panspermia or that life could arise on other planets, suppose that asteroids brought them to earth.

Sugar molecules have been found in interstellar space for the first time. The finding adds further evidence to the idea that early life on Earth may have benefited from complex sugar molecules arriving from elsewhere.

Sugars arise from chemical bonds among carbon, hydrogen and oxygen. Besides serving as an energy source, certain sugars are fundamental building blocks of RNA and DNA, the genetic material found in every living cell. However, there has long been a chicken-and-egg problem: living organisms make sugars with enzymes, but experiments recreating conditions on pre-life Earth have yielded relatively few.

Hidden store of manganese may have helped Earth get its oxygen

Computer simulations have uncovered a new manganese compound that could exist deep in Earth’s mantle and may be connected to the process that gave our atmosphere oxygen.

When did the Earth get its oxygen? According to a new study, it may have got it from manganese that may have been present deep before in the Earth’s mantle.  Some evolutionists believe that manganese was present in the early stages of the Earth’s history.

Deep below our feet, manganese may exist in a form we have never seen before, and this underground source of the metal could have played a role in the story of how Earth got its oxygen.

Until about 2 billion years ago, Earth’s atmosphere barely contained any oxygen. Then came the Great Oxygenation Event (GOE) when oxygen produced by photosynthesizing microbes started to accumulate, spurring development of more diverse forms of life and changing the planet.

Manganese is thought to have been a crucial component in an early version of photosynthesis, before the evolution of the oxygen-producing pathway that is widespread today. In Earth’s crust, manganese is commonly found in oxygen-containing ores, which started to accumulate at around the same time as the GOE.

Europa may have less oxygen to fuel life in its seas than we thought

It is a hard for evolutionists, for “Jupiter’s moon Europa may be less ripe for life than we thought. Although it has an ocean of water beneath its icy shell, the frigid moon may be short of the oxygen necessary to sustain life as we know it.”

They just taught that Europa was ripe pr life. Now they are disappointed.  

“Oxygen is produced on Europa when radiation hits its surface and splits the water ice there into its constituent parts, hydrogen and oxygen. Models of that process have suggested the rate of oxygen production could be anywhere from 5 to over 1000 kilograms per second.

Jamey Szalay at Princeton University and his colleagues used data from the Juno spacecraft, which flew just 353 kilometres above Europa’s surface in 2022, to make a new estimate. They found oxygen is only being produced at a rate of about 12 kilograms per second on the surface – right at the low end of previous estimates.

“In some sense, the shell is like a lung for Europa. It’s continuously generating oxygen,” says Szalay. “That being said, we can’t speak to what happens after the oxygen is produced on the surface – it’s still a question how much of it could get into the ocean.”

Phytoplankton are becomng scarce

Phytoplankton are mostly microscopic, single-celled photosynthetic organisms that live suspended in water. Like land plants, they take up carbon dioxide, make carbohydrates using light energy, and release oxygen. They are what is known as primary producers of the ocean—the organisms that form the base of the food chain.

Now, phytoplankton are becoming scarce,

Despite their diminutive size they pay a key role in keeping our oceans healthy. They are created by God to keep are planet in shape,

Evolutionists propose more photosyntesis, more life

Today, oxygen fuels much of life on Earth, but it wasn't always that way. Three billion years ago, this gas was scarce in the atmosphere andoceans.

 

Knowing why oxygen became plentiful could illuminate the evolution of our planet's flora and fauna, but scientists have struggled to find an explanation satisfying to all.

 

Now, a research team has proposed a novel link between how fast our planet spun on its axis—which defines the length of a day—and the ancient production of additional oxygen.

Their modelling of Earth's early days, which incorporates evidence from microbial mats coating the bottom of a shallow, sunlit sinkhole in Lake Huron, produced a surprising conclusion: As Earth's spin slowed and led to longer days, that could have triggered more photosynthesis from similar mats, allowing oxygen to build up in ancient seas and diffuse up into the atmosphere.

 

 Why did the Earth freeze to death in its infancy?

Some Evolutionists Believe That The Earth Lost All Oxygen Ages Ago

Some evolutionists think that the Earth lost nearly all of its oxygen ages ago, They think that a halting process that took 100 million years longer than they previously believed.

At its begIning, 4,5 millions years ago, the atmosphere contained almost no oxygen,  But 2.43 billion years ago, something happened

Oxygen levels started rising, then falling, accompanied by massive changes in climate, including several glaciations that may have ccovered the entire Earth wIth ice, 

This is contrary to the view  that the Earth makes its waters itself.

It would be easy to solve the problem by giving up the belief in millions of years.
