Ptolemy set the basis for the geocentric system in the antiquity, and it was widely accepted as true, mainly because the religious leaders thought that it accurately matches the basics of the Bible, and later the Koran. The Ptolemaic geocentric system was not accurate though, as it was putting the Earth as the center of the universe, with the sun, moon, stars, and other planets all orbiting around it.
It was not until the late Middle Ages when Copernicus created a theory that it is the sun that is the center of the universe not he Earth, unfortunately he did not had a proof. Galileo though made a new invention, the telescope, which helped him prove the theory of Copernicus, and was also an invention that was providing proof for it. His research and findings were suppressed by the church, but gradually they managed to get out in the public and show the world the truth.

Esto debido a que los nómadas son cazadores y recolectores, aunque algunos también son pastoralistas, y otros ocasionalmente practican algo de agricultura. Los nómadas necesitan cambiar de lugar de residencia en el momento en que los recursos naturales que necesitan se agotan en un lugar específico.
Las personas sedentarias en cambio, basan su alimentación en la agricultura, y tienden con el tiempo a construir civilizaciones. Como la agricultura permanente requiere de un gran cuidado, éstas personas necesitan vivir cerca a sus cultivos con el fin de poder sembrarlos, mantenerlos, y cosecharlos.
