Who invented the Phoenician alphabet?

Answer 1

The Hebrew alphabet The Hebrew alphabet developed alongside several other alphabets in the Middle East, more than 3000 years ago, but it's not known what individuals were involved. There was a different Hebrew alphabet in use prior to 3000 years ago, which may have developed as early as 8,000 years ago. The creators of that alphabet are also unknown.
Nobody knows, but it was adapted from the Phoenician alphabet more than 3300 years ago.

Scientific Answer
The Hebrew alphabet developed alongside several other alphabets in the Middle East, more than 3000 years ago, but it's not known what individuals were involved. There was a different Hebrew alphabet in use prior to 3000 years ago, which may have developed as early as 8,000 years ago. The creators of that alphabet are also unknown.

Traditional Answer:
Our tradition states that Hebrew was the language with which God created the world (Rashi commentary, Genesis 2:23, quoting the midrash); and it is the language with which He gave the Torah. The creator of the Hebrew alphabet was the creator of the universe.
Since it was considered a holy language and was used for prayer and the teaching of religious tradition, it was not used or written in mundane contexts and wasn't taught to just anyone. It was handed down from individual teachers to disciples as part of the original tradition; and the same goes for the art of writing itself (letters on parchment, as opposed to cuneiform or heiroglyphics). Thus, certain Hebrew Psalms (92 and 139) and teachings are attributed to Adam, the first man. The wider public, most of whom descended relatively quickly into idolatry and sin, were not given access to the treasures of the original tradition, alphabet, etc., since by their actions they implicitly repudiated it.

After the Flood, the spoken Hebrew language had a brief period in which it was generally known, thanks to Noah (see Rashi commentary on Genesis 11:1). This is why many hundreds of Hebrew words have cognates in languages as diverse as German and Japanese. The English alphabet, which secular scholars trace back to the Phoenicians, is according to our tradition actually one step older than that: it is from the Hebrew aleph-bet, which those of the Phoenicians and Greeks closely mimic.

After the Flood also, the knowledge of Hebrew eventually declined (see Genesis ch.11) and was preserved only among the Western Semites, the ancestors and cousins of Abraham. Eber, from whom our word "Hebrew" (Ivrit) is named, was a Semitic descendant of Noah and ancestor of Abraham. He was one of the major transmitters of the original traditions. He is credited with having broadened the Hebrew language, and some Hebrew grammatical constructs are attributed to him by certain Jewish researchers.

As time passes, languages grow and adapt. Thus today we can identify words and types of usage that go all the way back (and these are the ones that are most likely to have widespread cognates). And then there are Late Biblical Hebrew; the Hebrew of the Mishna; Medieval Hebrew, and so on. All of these have a broad overlap, but each has introduced its added vocabulary words and usages. Today, Torah-Hebrew includes some words that were borrowed from the Persian, some words taken from ancient Greece, Aramaic words, etc.
