I am twelve years old and want to know how life began on earth.

I am 43 years old and so would I! Scientists believe that lightning striking the atmosphere of the earth long ago caused certain simple chemicals like ammonia to form into more complicated chemicals that could lead to living cells. These chemicals then could hook together in chains to form molecules that direct life, such as RNA and DNA. One theory also says that fats in the primitive ocean acted on by waves, formed large globules enclosing these life directing chemicals, and that these structures eventually formed primitive cells. Then inside the cells, conditions could evolve to allow the chemistry of life to work better and better, and so on.
