Life, a miracle in the universe appeared around four billion years ago and we humans only 200,000 years ago, yet we have succeeded in disrupting the balance that is so essential to life. At the beginning, our Earth was just a cluster of fire and now life is a chain of innumerable living beings that have succeeded another on Earth for almost nearly 4 billion years. Even today new volcanoes begin to scape our landscapes and offer a glimpse of what our Earth was like at its birth. During birth, the Earth’s perfect balance enabled it to conserve water in liquid form and cut channels like the veins of a body. The rivers then tore minerals from the rocks and gradually added them to the fresh water of the oceans and the oceans eventually became heavy with salt. Primitive life forms also still exist in the globes hot springs, which give them their primary colors. The blue green algae are a vital ancestor of all yesterdays and todays plant species and have changed the destiny of our planet by transforming the atmosphere. Thanks to the microorganisms’ accumulated shells or strata, the carbon drained from the atmosphere and other life forms could develop, therefore it is life that altered the atmosphere. As for the Earth’s water cycle it is looked at as a process of constant renewal and is never broken, therefore there’s always the same quantity of water on Earth at all times. Water comes in three different forms, solid, liquid, and gas. Liquid forms as running water, gaseous as vapor, and solid as ice. As for plant life, they feed off the sun’s energy, which enabled it to break apart the water molecule and take the oxygen and oxygen filled the air. The engine of life is linkage, everything is linked, and nothing is self-sufficient. Water and air are inseparable and united in life and in the chain of species trees are a pinnacle or perfect living sculpture. They are the only natural element
