Between 3700 and 2500 million years ago, the Earth was born. Nothing was as it is today, neither the continents, nor the oceans, nor the atmosphere. In those times, the atmosphere was crossed by electric storms, and ultraviolet rays of the Sun. These phenomena transformed the substances that were present, by means of chemical reactions, into macromolecules that were able to reproduce and feed themselves. Life was born! 


A bag of bananas!
