When was the Hebrew language born?

Answer 1

Nobody knows. There is archaeological evidence for it going back 3000 years, but it is most likely much older than that.

Even from a modern linguistic point of view, the ancient Israelites were speaking an ancestral form of Hebrew long before the Torah was written down, though it's not truly known how long.

The Hebrew spoken prior to the 10th Century BCE is known today as Proto-Hebrew, and it wasn't distinct from ancient Ugaritic or ancient Canaanite.

All of the Northwest Semitic languages, including Hebrew, started to become differentiated during the Iron Age (1200–540 BCE). Prior to 1200 BCE it could still referred to as Hebrew, particularly when referenced as the dialects of the Jewish ancestors, though it's not known how it differed from the Archaic Biblical Hebrew of the Torah.
