The accepted timeframe for the beginnings of life on Earth is now being questioned by a Curtin University of Technology led team of scientists, after finding a key indicator to the earliest life forms in diamonds from Jack Hills in Western Australia... The Curtin led team's discovery of very high concentrations of carbon 12, or "light carbon" within these crystals is remarkable as it is a feature usually associated with organic life... Evidence for ancient life stretches back in time to at least 3.5 billion years ago, in the form of single-celled organisms that did not require oxygen. The discovery of light carbon in the Jack Hills crystals raises the question â did a simple life form exist on Earth 700 million years earlier than previously thought? ...In 1983, a Curtin project team discovered extremely old zircon crystals in a collection of rocks located between Meekathara and Carnarvon. Twenty years later, the oldest diamonds were unexpectedly discovered in these rocks by many of the original team.

If 700 million is the margin of error, then it’s entirely possible, according to these scientists, that life actually began much later, confirming biblical accounts.

Will someone with a brain really try to comprehend that statement?
Creationists are crazy for believing a young earth 6-10,000 years ... but 700 million is entirely within the ken of comprehension?
My God is Jehovah. and "their" god is 'million'.
LOL!

Look at Deuteronomy 23: 2.
Okay, now this is a bit of an X-Planets topic:Carbon ratios suggest life present early in Earth's daysThe researchers also suggested an even more intriguing explanation: Life processes produce residues with greatly reduced C-13 ratios. If the low C-13 ratios in the microdiamonds from Australia were produced by living organisms, there was life on this planet more than 4.2 billion years ago, almost as soon as it formed.

That suggests life might be present in many parts of the universe.

Okay, now this is a bit of a Catastrophism topic:Carbon ratios suggest life present early in Earth's daysThe microdiamonds had surprisingly low ratios of C-13. One possible explanation is that they represent meteorites that bombarded the planet early in its history. Many meteorites are characterized by low C-13 ratios.
