The First Life On earth Appeared 270 million years earllier than originally thought

The Earth was formed around 4.54 billion years ago and with this new research in it shows that it was only 440 million years later that life first began. Of course these are massive numbers and very difficult to get your head around but it may mean that life in the rest of the Universe could be out there. “Modern Humans” have only been around for 250,000 years – just the  blink of an eye in these  numbers. The new research was carried out through the analysis of around 10,000 Zircon stones found in Western Australia.

Zircons are known as time capsules because they preserve materials from their environment as they form.

Out of the thousands of zircons they studied they found 79 which looked like they might contain graphic, which is made of pure carbon which life depends on.

After studying them all they found a single zircon with graphite in – which turned out to be 4.1 billions years old.

The study’s co-author, Mark Harrison, a geochemist at the University of California (UCLA), told the Live Science website: “It was nerve-wracking to manipulate the sole tiny zircon fragment — about half the width of a hair on your head — containing the graphite inclusions.

“20-years-ago, this would have been heretical; finding evidence of life 3.8 billion years ago was shocking.

So, life started  on Earth over 4 billion years ago but just how did this happen, the video below  helps explain this:
