We all have heard or read about how the earth started its life spam, but here is another better than the one we were told.
Over a billion years ago the earth was just a tiny piece of rock floating in space,over time its been bombarded by meteor of different sizes creating a huge magnetic ball rotating on its Axis.
Over a period of time this ball has increasingly grow in mass and magnitude roughly in a spherical form making a revolution every 365½ days round the sun.
But still its on unhabitable,its too hot for life to dwell in,after a thousand years it began to freeze because of the atmospheric condition in space and appeared like a huge floating ball of ice in space but still it cant allow the organization of life.
So few thousand years later, after direct contact from sunlight the ice begins to melt forming seas and oceans larger than the ones present now,this oceans were habitable hosting small planktons and plankton like creatures,
This is how life first started.
This plankton like creatures exhibit different forms of feeding,so some began to grow larger than the other, having different characteristics an growing more than one cells.
They feed on the smaller organism,became large enough with adaptive organ's to move out from water to land,this were one of the first orgnisims to step on land.
Later others follows and those who were small or exhibits slow or no adaptive organ's remains in the water forming our fishes and the aquatic life we know today.
Those first animals to step on land became larger and more adapted than others so the stay top of the food chain,(mostly carnivores)while smaller animal or less adapted ones stays bellow the food chain and still struggle to keep its existence till now.
...... What a strife on Earth......
