Earth’s Early Steps

Some 3.5 million years ago, what happened that day, would not be witnessed by human beings, for their day had not come, they did not exist.

A dark brown head with small eyes looked from side to side in a cautionary movement, not wanting to be prey for some hunter animal.  This new animal to the food chain, with its flat-topped head, low forehead with a pronounced ridge running above its eyes, with a flattish styled nose, appeared different, no dangling arms existed.

As it slowly advanced through the long grass, satisfied no danger was obvious, it rose up, walking on two legs, not the customary four.  The creature, the animal was the next step in the evolution of mankind was female and belonged to the Australopithecus Afarensis group of mammals, the first known creature to be bipedal (walk on two legs).

These Australopithecines shared many physical characteristics with gorillas and chimpanzees; they had taken the first steps on the evolutionary path to the modern day man and woman.

If we go back 15,000 million years ago, it is believed that a cosmic fireball exploded in space, creating many galaxies. 

Approximately 4,600 million years ago Earth was formed, and men of science have deduced that the creation of humanity started on the 23rd October 4004 BC.

It is highly unlikely, that at the point of Earth’s creation, the atmosphere would have been a safe place for human, plant and animal life.  Planet Earth would have been waiting for the process of Photosynthesis to commence, leading to the release of oxygen into the atmosphere.

Photosynthesis: (Life on Earth relies on Oxygen to survive, and marine plants are known to produce seventy to eighty per cent of the oxygen in the atmosphere.  Most marine plants, found in our water’s are single celled photosynthetic algae, of which there are some five thousand species.

Earth’s oceans are known to cover, some seventy percent of this planet, and land the remaining thirty per cent.

Think of the plants, which live below the waterline of our oceans, rivers and lakes, for they are providing oxygen, for our atmosphere.

An interesting thought, if man continues to pollute our oceans, he is killing of marine plants, which reduces oxygen in our atmosphere, which could destroy mankind in the future.)

Single-celled organisms would be the first phase in the process, followed up by multi-celled organisms, which evolved into fish.  As our evolution of Planet Earth evolved, many changes took place, before our very eyes.  Large expanses of green fields would spring up, mountains were formed, rivers, lakes and seas filled with fish.  As we move forward Amphibeans evolved from fish, and into reptiles able to sustain life on dry land.  Birds and mammals evolved from reptiles, and human beings would be the final step in the evolution of mankind, evolving from mammals.
