Soon or later we are going to ask ourselves seriously where we come from? That time did come to me more than a year ago, and then I started researching more about it. I looked on both religious and scientific view points, and I ran into 2 scientific theories. The first one is the big bang theory that describes how the universe was born, and the second one is the evolution theory that describes how life was born on Earth.

What does the evolution here mean?

It is a process by which, species (or lives) have changed their characteristics (traits) over times and passed the new traits from one generation to the next. The traits are such as eyes color, hair color, height, skin color, less or thick body hair, blood type, bird's beak, color of flower, and etc. Overtime the changes could create a new specie. The change is mainly cause by natural selection. The detail of natural selection are not covered here at this time.
