6And God said, “Let there be a vault between the waters to separate water from water.” 7So God made the vault and separated the water under the vault from the water above it. And it was so. 8God called the vault “sky.” And there was evening, and there was morning—the second day.

A tantalizing new study published in the journal Nature Astronomy suggests that Mars might have been habitable before. Researchers from Hong Kong and China found that the Martian atmosphere might have evolved in the same way the Earth’s atmosphere did – it was once filled with toxic gases that warmed the planet, then a great oxidation event that was potentially fueled by photosynthetic organisms deposited oxygen into it.

Studying the Martian atmosphere

Earth went through a process called the “Great Oxidation Event” (GOE) two to three billions of years ago. The GOE gradually deposited enormous amounts of oxygen into the atmosphere, leading to the emergence of complex life forms.

Scientists agree that photosynthetic cyanobacteria were responsible for the GOE. These microorganisms existed millions of years before the event and managed to thrive despite Earth’s then “reduced” atmosphere, which was made up mostly of reduced gases like methane, ammonia and hydrogen sulfide. While humans would suffocate breathing these gases, cyanobacteria would be able to subsist on sulfides.

“On Earth, oxidation happened because of the evolution of oxygenic photosynthesis,” said Joseph Michalski, a professor of planetary science at the University of Hong Kong (HKU) and one of the study researchers.

Because of the GOE, Earth now has an oxidizing atmosphere that causes exposed rocks and compounds to rust. Mars also has an oxidizing atmosphere, which is the reason why the planet looks ruddy. But past studies showed little evidence that Mars was reduced before becoming oxidized.

Now, Michalski and his team suggest that the Martian atmosphere was likely reduced eons ago. They arrived at this conclusion after studying ancient rocks on the planet’s surface through remote sensing and examining data collected here on Earth. Their analysis showed that ancient Martian rocks exposed at the surface had been weathered under reducing conditions.

Mars might have been habitable before

Can anyone show any scientific absolute proof God doesn't exist?

Lol how can you proove something that is smarter than us? Its funny to see a Dog trying to Catch its tail and never catching it tho.

Science is based on Codifiying and explaining to make it comprehensible for a Human Being. How do you explain something that is not codified or is infront of every move you make ?

The only proof we will ever have is if the Creator decides to showcase himself to us

Which does piss me off

You keep repeating these over and over again because you can't admit to yourself that they are based on fallacies, and you hope that if you repeat them enough they will magically become true.

^^^ That's why atheism is a religion. Atheists have faith in a whole bunch of things that they twist into what they want to hear and see, rather than what exists.
