1. The Autochthonous Theory: This theory proposes that the Greeks originated from the land itself and were not migrants from other regions. According to this view, the Greeks were indigenous to the Greek peninsula and the surrounding areas, and their culture and civilization developed independently without significant external influences.
2. The Migration Theory: This theory suggests that the Greeks originated from various parts of the world and migrated to the Greek peninsula over time. According to this view, the Greeks were originally a collection of different groups who gradually settled in Greece, bringing their own languages, customs, and traditions, which eventually merged to form the distinct Greek civilization.
