Question: What Was The First Thing On Earth

Hi Jeff,

The first life on Earth would have been very simple single cell organisms, formed from the joining of organic molecules, themselves formed from basic ameino acids (proteins) that gathered in what is called the Primordial Soup.

After that the life developed to be bigger, so multi celled organisms such as large algal mats and eventually basic plants and animals. After about 2 billion years of this happening, the concept of hard parts like bones and shells developed and from there we begin the fossil record about 600 million years ago.
