One of the most common questions that people have is how life began. The answer will depend on what you believe in. One thing is certain is that life dates back to millions of years ago. However, there are fossils that show that Earth could have been around billions of years ago. It is hard to get an accurate date because there is not much evidence to give an exact date.
From there, how life starts depends on what you believe in. Some people believe that evolution occurred from animals. This idea became popular with Charles Darwin. Others believe that humans were first and then animals, which is a philosophy that many Christians believe.
There has long been an ongoing debate between scientists about how the earth came to be. Excluding all religious theories, some scientists say that the planet began about 2 billion years ago from the low waters. A group of atoms bonded together and formed a new type of molecule, like a giant molecule bigger than all the other atoms groups.
Some scientists say that life began in a volcano, and others say it started under the ocean floor. Another theory is that the building blocks of life were first created somewhere in the universe and came to the earth enveloped in meteors. Scientists contemplate that the existence of molecules preceded genetic material as we know it today.
These molecules are replicated and come abruptly from miscellaneous material, yet there is no evidence that these molecules ever existed. Some believe in mutation, while others say that animals and humans developed from a single fertilized egg.
To begin with, life began millions of years ago. It is believed that the dinosaurs lived over 250 million years ago, but there were fossils that are believed to be dating back to billions of years ago. Over 4.5 billion years ago, Earth is believed to have been formed. There have been several people who have conducted experiments and have done scientific research to determine when life really began.
Charles Darwin believed that life began through the evolution of animals. Many elements are considered when dealing with the origins of life. Life can mean different things. It can mean the beginning of the life of the human being or the beginning of the life of animals. It could also mean the beginning of Earth.
