Dalawang theory ang pinaka pinaniniwalaang pinanggalingan ng Tao; Creation at Evolution. Classic na tapatan ng science at religion. Para sa mga mas naniniwala sa science, evolution daw, at galing tayo sa unggoy. Sa mga mas naniniwala sa religion, creation daw, at ginawa tayo ni God in his image.
Sa dalawang theory na yan, wala kaming pinapanigan. Parehong walang solid na katibayan, at pareho din namang may posibilidad na nangyare. Pero hindi ba masyadong convenient kung basta-basta na lang tayo maniniwala sa kahit alin dyan? Theories lang yan 'e.
