Here are some common explanations for the symbolism of the 12 stars:

* The 12 stars represent a perfect and complete whole: The number 12 has a long history of symbolism, often representing completeness, perfection, and unity. In Christianity, there are 12 apostles, and in astrology, there are 12 zodiac signs.

* The 12 stars represent the ideals of Europe: The stars are often seen as representing the ideals of peace, freedom, and democracy that the European Union stands for.

* The 12 stars represent the European people: The stars can be seen as representing the unity and solidarity of the people of Europe, regardless of their nationality or origin.

It's important to note that there is no official explanation for the meaning of the 12 stars. However, the symbolism of the stars is widely understood and accepted as representing the unity and harmony of the European Union.

The number of stars doesn't represent the number of member states. The flag was designed in 1955 with 6 stars, then adapted to 12 stars when the European Economic Community expanded in 1985, but it's important to remember that the 12 stars symbolize unity, not the specific number of member states.
