I like to Study Astronomy, Geology, History, and Futurism and the best way to handle it is to do it One-step for mankind and to adapt the knowledge I received into the creation of creativity and the world One-leap for humanity.
The time of Earth
At the beginning with the formation of our known planet earth many the known species of animals animals didn't exist at that time since most of the prokaryotic microbes and bacteria when the earth formed did not evolve yet living many of the species we know if of didn't arrive at that time prokaryotic microbes were the only organisms thriving on earth. Different kinds of bacteria roamed around the Eco-systems most of them dissolved minerals to eat and migrated there way around the continents until lots of them ended up in different regions of the world, the theory of prokaryotic microbes is they don't carry a membrane-bound nucleus their DNA is circular and don't have a shield of skin.
The Grand Beginning
Since the dawn of time there a was an empty space then a huge supernova brought a universe that lies the outer worlds of imaginations that we can think there are other possibilities of whole new galaxies thriving in different regions of the known universe holding knowledge that basks in the cosmos, since time many anomalies lie hidden in the worlds of space. Throughout the history of the past many terrestrials began to shape bringing rocks and gases clumping then together that formed huge terrestrial giants, but back in the early existence of the universe well..... there wasn't anything to explore.
