The first life apeared on earth some time around 4.4 billion years ago.
Yes
The earliest life forms on Earth were single-celled microorganisms like bacteria and archaea. These simple organisms emerged around 3.5 to 4 billion years ago in the ancient oceans of the planet. They played a crucial role in shaping the environment and paving the way for more complex life forms to evolve.
how
The earliest forms of life appeared during the Archean Eon, which began around 4 billion years ago. The first life forms were simple, single-celled organisms known as prokaryotes, such as bacteria and archaea. Evidence suggests that these organisms thrived in various environments, including hydrothermal vents and shallow seas, laying the foundation for more complex life forms to evolve later.
The earliest ones still around are stromatolites, but there were lots of earlier life forms.

Bulbusaur it evolves to venusaur at level 32 while charmander and squirtle evolve to charizard and blastoise at level 36.
The earliest stage is being in the egg. Then comes the caterpillar stage.
