We may think that our world is very old but, in fact Earth was born 4.54 billion years ago. For the Universal Calendar these are just a few seconds.
When Earth was formed It was just a big ''magma ball''.It definetely couldn't been inhabited.
In many milions of years the atmosphere formed and the clouds started to appear.Then, for another milions of years it rained constantly. It's hard to believe but, that water formed the oceans we know today.
The water was a proper place for the evolution of beings. The first forms of life on Earth were...
...BACTERIA.
Bacteria was truly the first form of life. It didin't look very capable for life but, it was it is and it will be the strongest being.
