How is the Greek alphabet different from the Finnish one?

The Phoenician alphabet originated in the middle of the 2nd millennium BC. Its distinctive feature was the presence of 22 vowels. It was much easier to learn than the Egyptian or Sumerian alphabet. Over time, the Greeks borrowed their alphabet from the Phoenicians and introduced vowels there. We can say that they logically continued the development of this ancient alphabet, since the lack of vowels among the Phoenicians was the main drawback. But the Greeks eliminated this deficiency and created the ancient Greek alphabet.
