"If you walks into any village 3 thousand years ago, there is a high possibility that the first man you met is your great great great grandfather."
Adam and Eve is human first human ancestor, as the Bible had stated. We just need a scientific method to prove it, and confirm our logical thought. Human just cannot accept religious teaching as it is.
Even now we have a scientific prove that human are from a family, does this end all historical conflicts and solve all humanity problem?
You don't have to pay $30 to know that. (Link)
