Beginning Of Life On Earth at Life

Beginning Of Life On Earth. Earth was created 4.6 billion years ago after an explosion, some strong winds, and gravity worked together to develop all of earth's layers. The timeline of life on earth begins over 4.5 billion years ago.

The earliest evidence for life on earth arises among the oldest rocks still preserved on the planet. Life arose naturally through a long succession of chemical steps that were bound. Based on their results, the authors made a conclusion that a popular theory on the emergence of life on earth, in which lightning strikes interact with certain gases (notably ammonia and methane) to create amino acids—the building blocks of life—seems much less likely.

Advanced forms of life existed onearth at least 3.55 billion years ago. Earth is about 4.5 billion years old, but the oldest rocks still in. There were lots of hypothesis regarding the origin of life on earth. The earliest physical evidence so far found consists of microfossils in the nuvvuagittuq greenstone belt of northern quebec, in banded iron formation rocks at least 3.77 and possibly 4.28 gya.
