Scientists have found evidence of a huge asteroid that struck the Earth early in its life with an impact larger than anything humans have experienced.
Tiny glass beads called spherules, found in north-western Australia were formed from vaporised material from the asteroid impact, said Dr Andrew Glikson from The Australian National University (ANU).
"The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes, it would have caused huge tsunamis and would have made cliffs crumble," said Dr Glikson, from the ANU Planetary Institute.
"Material from the impact would have spread worldwide. These spherules were found in sea floor sediments that date from 3.46 billion years ago."
The asteroid is the second oldest known to have hit the Earth and one of the largest.

We are all going to die. Actually that is true.
Even then, women and minorities were hardest hit.
All of a sudden, I want some bacon.
Actually, a spear point and a cutting tool made of the chert (flint) might get you that bacon.
Thanks JimSEA.
It has been 3.46 billion years. Well no wonder I forgot about it.
All the weird animals they have in that country must have come from DNA that was on the meteor.
