Origin of “Life” on earth needed only 3 essential components – sunlight, minerals of earth and water. Life appears to have begun in water few billion years ago (Propelled by a Supreme Entity we may call – God / Nature) – first in the form of single cell bacteria, thriving by consuming dissolved minerals of water. Concurrently or later, plant life also began on earth in the form of Lichen (Algae) – propelled by the same supreme entity – by combining minerals and transforming it into plants by using water as the main element for ingesting food, and using sun light as the source of energy for the process.
Evolution of life progressed with time, to higher forms from the lower, both in water and on earth. On careful observation we can broadly find two main categories of life on earth – animals that can move on their own from their place of birth to another location in search food for survival – and the plants which stay where they are born and draw food from the minerals of earth with the help of water, with no capability to move to another location. This resulted in the plants becoming the source food for the animals – as plants cannot run and escape. Read the rest of this entry
