Star of David, the hexagram that is not related to Jews!

A hexagram (Greek) or sexagram (Latin) is a six-pointed geometric star figure, {6/2} or 2{3}, the compound of two equilateral triangles. The intersection is a regular hexagon.
It is used also in other historical, religious and cultural contexts, for example in Hinduism, Occultism and Islam and in last centuries as Jewish identity too.
In mathematics, the G2 root system is in the form of a hexagram.
The hexagram, as a simple geometric shape, like for example the triangle, circle, or square, has been created by various different peoples with no connection to one another. But there is a belief that King David had used it as an emblem. Some say that Solomon had it on his ring too.
The hexagram is a mandala symbol called satkona yantra or sadkona yantra found on ancient South Indian Hindu temples. It symbolizes the nara-narayana, or perfect meditative state of balance achieved between Man and God, and if maintained, results in "moksha," or "nirvana" (release from the bounds of the earthly world and its material trappings).

It's said that in antique papyri, pentagrams, together with stars and other signs, are frequently found on amulets bearing the Jewish names of God, and used to guard against fever and other diseases. But curiously the hexagram is not found among these signs.In the great magic papyrus (Wessely, l.c. pp. 31, 112) at Paris and London there are twenty-two signs side by side, and a circle with twelve signs, but neither a pentagram nor a hexagram.

Conclusion:
The Hexagram is an old symbol and is not related to Jews at all. It seems that after Hitler usage of this occult symbol attempting to shame the Jewish people; today they are using this symbol as their own. There are also some Jews that don't believe in the Hexagram because of the reason. And about Israel we should know that the symbol is the 7 candle menorah. It seems that the usage of the Hexagram in the Israeli flag is more related to the secret societies of Britain. They mostly believe in the Zionism Idea – not mentioned in most cases - and developing a Zionist Government led them to use the symbol on the Israel Flag.
