answer:The main inhabitants of Crete during the time when the ruins were constructed were the Minoans.

answer:Certainly! The Minoans were an ancient civilization that existed on the island of Crete, located in the eastern Mediterranean Sea. They are considered to be one of the earliest and most advanced civilizations of Europe, predating classical Greece by several centuries. The Minoans were known for their impressive architecture, particularly the construction of massive palace complexes such as the famous Palace of Knossos. They were also skilled artists and craftsmen, creating beautiful frescoes, pottery, and jewelry. The Minoans had a complex social hierarchy, with a ruling class overseeing a society that was largely focused on agriculture and trade. They were also known for their religious practices, which often centered around worshipping a mother goddess figure. The downfall of the Minoan civilization is still somewhat of a mystery, but it is believed that a catastrophic event, possibly a volcanic eruption or earthquake, may have led to their decline. Despite this, their legacy lives on in the impressive ruins that can still be seen on the island of Crete today.
