THE 25 BIGGEST TURNING POINTS IN EARTH’S HISTORY

Hmmm ;)

Hmmm ūüėČ

Yes they are big and fundamental in how we became and what were are today.

Below is a link to the 25 biggest turning points in earth’s history. Science is continually ¬†shining an almost celestial light to illuminate the path out of ¬†the darkness of our ignorance ¬†in understanding our ¬†existence. Exciting discoveries are being made. It is now thought that life on our planet ¬†began in deep space.

The cloud of gas and dust that eventually formed our sun and solar system was created over 5 billion years ago  by the massive  death throes  and explosion of a massive star over 10-100 times the size of our sun in an event known as a supernova. This cloud  contained all the elements we know of today and make us up.

So we are literally  star born!

Chemical precursors  to life have been found in comets and asteroids that were and still are  around  from 5 billion years ago at the birth of our solar system, from this cloud.

Some of these objects  were very many at the beginning  and  their close orbits meant that they  regularly collided with the  forming earth.  Some of these comets and meteorites  seeded our planet  with chemicals and materials which over millions of years evolved into multi cellar life, primitive bacteria and thenceforth to us billions of years later.
