Life on Earth
Just read a small write-up in my paper which says scientists at Rice University in Texas have simulated the planetary crash they believe caused life on Earth.
They also believe it was a crash 4.4 billion years ago, that formed the moon.
The 'giant impact hypothesis' says we smashed into a Mars-sized planet which deposited life-essential elements on earth.
That includes most of the nitrogen and carbon found in living things, including humans today.
Debris from the crash formed the moon, according to lab simulations.
They are saying this was "consistent with all the geo-chemical evidence."

We sometimes hear warnings that meteors are coming closer to Earth, and I can't help but wonder if that is what will finish us again one day.
