Good stuff Chrissie, here is more in that vein;
Gen 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath5397 of life; and man became a living soul.
Lifeless body + breath of God = living soul
Gen 6:17 And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath7307 of life, from under heaven; and every thing that is in the earth shall die.
Job 33:4 The Spirit7307 of God hath made me, and the breath5397 of the Almighty hath given me life.
Act 17:25 Neither is worshiped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath,4157 and all things;

very similar to;

Ecc 12:7 Then shall the dust return to the earth as it was:, and the spirit7307 shall return unto God who gave it.
The spirit described here is the breath of life, as in the scripture Chrissie quoted;
(Ecc 3:19 For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath(7307); so that a man hath no preeminence above a beast: for all is vanity.)
When all souls die (man or beast) the breath of life (spirit) goes back to where it originates, to God, inanimate once again, until the resurrection.
