Depends on which cultural/religious perspective you are looking from. According to Christian lore - Adam was the first person; Chinese lore holds that Pangu was the first, and in Hinduism it was Manu. Each one is different.
The first person to be created, was Adam. Nobody knows his last name (if he even had one! :-). God created him out of the dust in the ground. Hard to believe? Well what happens to people's bodies when they are lying in the grave? They turn back to dust!! So it's pretty believable for me! :-D
