Migration of Man

This is truly amazing. The fact that Adam & Eve were born on the border of Kenya and Ethiopia and from there migrated throughout the world really astonishes me. Especially passing the Bering strait in order to migrate to the Americas. What really really really leaves me questioned is. What drove them ? Why did they migrate? Why wander through really difficult lands? Is this one of the defining factors of the human race? Our curiosity, our need to explore new territory (not just land)?

Amazing!
