At this point in time, the land of Canaan (which includes modern-day Israel, Palestine, Lebanon, and parts of Syria) is inhabited by a mix of Canaanites, Philistines, Israelites as major groups. Although, descendants of the Amorites, Phoenicians, Moab, Ammon, Tjeker, Geshur and Edom are very likely to be found among the crowds in the land of Canaan. 
The Israelites are the most documented group among all the mentioned, due to biblical recordings. Nevertheless, archeological findings prove they shared the land with the other mentioned groups.

At this point, it is high time we mention the term "Palestine"

The term "Palestine" has a long historical lineage, and references to the region as a distinct geographical entity between the Jordan River and the Mediterranean Sea can be traced back to antiquity. The earliest mentions of the term come from classical sources, including ancient Greek and Roman writings. 

It's very important to note that even though the term Palestine comes from the group known as Philistines, the area covered by what the Greeks and Romans called Palestine include all the groups mentioned before and not exclusive to the Philistines.  

Here are some early references to the term "Palestine":

1. Herodotus (circa 484–425 BCE):
    - The ancient Greek historian Herodotus is often cited as one of the earliest writers to mention the term "Palestine." In his work "Histories," written in the 5th century BCE, he referred to the region as "Syria Palaestina."
2. Ancient Greek Usage:
    - Ancient Greek writers, including Herodotus, Thucydides, and others, used the term "Palaestina" or similar variations to describe the coastal region between Phoenicia (modern Lebanon) and Egypt.
3. The Bible (Various Dates):
    - The term "Philistia" appears in various books of the Hebrew Bible (Old Testament), referring to the coastal region inhabited by the Philistines.
4. Hellenistic and Roman Periods:
    - After the conquests of Alexander the Great, the term "Palaestina" continued to be used by Hellenistic and Roman writers. During Roman rule, the region was officially designated as "Provincia Syria Palaestina."
5. Pliny the Elder (23–79 CE):
    - The Roman author and naturalist Pliny the Elder referred to the region as "Palaestina" in his work "Naturalis Historia" in the 1st century CE.

These references indicate that the term "Palestine" or its equivalent has been used for over two millennia to describe the general geographic area between the Jordan River and the Mediterranean Sea. The specific boundaries and political contexts associated with the term evolved over time, influenced by various empires and historical developments.
