Rudimentary life may have existed on Earth 3.95 billion years ago, a time when our infant planet was being bombarded by comets and had hardly any oxygen, researchers said Wednesday.

…

A team presented what they say is the oldest-known fossil evidence for life on the Blue Planet—grains of graphite, a form of carbon, wedged into ancient sedimentary rocks in Labrador, Canada.

…

For the new study, Komiya and a team studied graphite, a form of carbon used in pencil lead, in rocks at Saglek Block in Labrador, Canada.

They measured its isotope composition, the signature of chemical elements, and concluded the graphite was “biogenic”—meaning it was produced by living organisms.

The identity of the organisms, or what they looked like, remains a mystery.More.

Life is making short work of current theorists.

awstar @ 9: Perfect. He (rvb8) will probably have to re-read your comment several times to understand his obvious mistake. Too funny.Truth Will Set You Free_{September 29, 2017

rvb8 answered this question: "How do we know what Seversky wrote is true?"
All you have to do with Seversky, is say, ‘did you write this?’ His functioning, living, material self, will repy. No such luck with the immaterial, dead, unfunctioning, several kinds of, Book!
Since rvb8's answer is false (asking Seversky if he wrote this won't in itself answer the question of whether it is true or not) then everything else rvb8 says needs to be considered highly suspect, using his own measurement of reliability.awstar_{September 29, 2017

Eugen @3, About knowing if you can trust what Sev wrote; he's alive, a person, and you can ask him. It's the other, 'written' stuff you should be questioning. You know, 'the truth', 'the Word', and, 'the Gospel' etc. All you have to do with Seversky, is say, 'did you write this?' His functioning, living, material self, will repy. No such luck with the immaterial, dead, unfunctioning, several kinds of, Book!rvb8_{September 28, 2017

Eugen, perhaps the comment @2 indicates that its author doesn't believe that what is written @1 is true and apparently doesn't like it either, but that's just an opinion, which doesn't affect the validity of the comment @1. I believe the comment @1 is true. However, my belief doesn't make the text @1 true. Some folks believe that the ultimate reality is defined by matter and energy. Others believe something else. I believe that the ultimate reality is defined by what is written @1. The truth is independent of what we belief is true. Certain things can be scientifically proven to be true or false with full certainty. This is not such case. Science domain is too reduced and limited for that. There are outstanding questions in biology that still remain unanswered because they're out of reach for current technology or because the gathered data is not well understood yet. But as technology progresses or computer models get refined, scientists should be able to peek deeper into the biological systems and make new discoveries that might clarify the big picture. The question of God is beyond science realm. It's a matter of faith. Atheists believe there's no God. I believe God reveals Himself generally to all people through His creation and specially to His people through the Christian Scriptures that were written by different authors that were inspired by God.Dionisio_{September 28, 2017

Eugen, the sentence @2 seems like a valid general principle. I don't have any problem with it. The truth is independent of what is written about it. The question is what is truth. The sentence @2 doesn't address it.Dionisio_{September 27, 2017

Actually, life existed before the Earth and the universe were created: It is written: In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him was not any thing made that was made. In Him was life [...] John 1:1-4Dionisio_{September 27, 2017
