NOVEMBER 1, 2015

Just recently, the University of California at Los Angeles (UCLA) combined a group of geochemists that unraveled the unknown history of our world. Having found evidence that Earth had already been inhabited by life 4,100 million years ago. This means that there was life on this planet 300 million years earlier than we had expected.

The evidence they had found suggested that life blossomed into existence just as the world was newly formed 4,554 million years ago. You can find all the work they had done that was published into the Proceedings of the National Academy of Sciences (PNAS).

“We need to think differently about the early Earth.” - Elizabeth Bell, Investigator from UCLA

This new study proclaims that life existed before the mass onslaught of the inner solar system that took place about 3,900 million years ago when a menagerie of intergalactic objects would crash into the very moon and earth themselves.

“Twenty years ago, this would have been heretical; finding evidence of life 3.8 billion years ago was shocking. Life on Earth may have started almost instantaneously. With the right ingredients, life seems to form very quickly.”  -Mark Harrison, co-author of the research found as well as the professor of geochemistry at UCLA.

The ultimate indication as to why their was life on earth previously was all due to the carbon that was found in pieces of zircons. With supervision from Elizabeth Bell, the team had studied over 10,000 pieces of zircons that formed from molten rocks located in Western Australia.

These zircons preserve the immediate environment around which led the team of researchers to believe that the zircons were acting as ‘time capsules’.

“If all life on Earth died during this bombardment, which some scientists have argued, then life must have restarted quickly.” States Patrick Boehnke, co-author of the research as well as a graduate student from Harrison’s classes.

“The early Earth certainly wasn’t a hellish, dry, boiling planet; we see absolutely no evidence for that. The planet was probably much more like it is today than previously thought.” States Harrison.

With the use of spectroscopy, the team was able to identify 656 zircons that contained dark specs. This technique allows them to see the molecular and chemical structure of ancient microorganisms in three dimensions. To their surprise, they had found graphite within 79 of the zircons.

“There is no better case of a primary inclusion in a mineral ever documented, and nobody has offered a plausible alternative explanation for graphite of non-biological origin into a zircon.” Harrison claims.

Only more and more questions stem from these findings. Hopefully, we can finally know the entire truth of our world that lived before us.
