Question

How long ago was the world created?

Answer 1

This is a very common question asked by everyone and we should have knowledge of this answer. We need to find out how many years ago our world was created. The answer will obviously be in years.

Complete answer:
There are many theories and hypotheses to show how the world originated. It has been always considered that when gases compressed under pressure abiotic components like water etc. were formed and slowly life began to form on this planet. So, the age of any object whether living or non-living is detected by a technique of carbon dating, although there are other techniques or processes but carbon dating is a reliable one. It has been predicted that dinosaurs lived $250$ million years ago. Some fossils date back to $3.5$ and some even $3.7$ billion years ago which means they existed even before dinosaurs came into existence (if we take the existence of dinosaurs as reference).
Scientists have conducted several experiments to conclude that all living beings are made of cells. Every species is made of similar kinds of the cell whether it is plant, animal, algae or fungi. But there is also the existence of single cellular organisms such as bacteria-which makes a theory that since every organism is made of more than one cell, single cells are the primitive ones and hence bacteria can be considered as an ancestor to many species. The age of this planet has been found to be $4.5$ billion years i.e. the earth is formed $4.5$ billion years ago.

Note: Scientists came to conclusion about the age of the planet by conducting numerous experiments and putting forth many theories. Therefore, the earth was created nearly $4.5$ billion years ago. Carbon dating is also a very important technique in knowing the age of a substance whether living or nonliving. According to the half-lives of material, their ages are calculated. Fossil studies are yet another way of studying the age of the earth.
