You are correct soul & spirit are two different things. As you stated man became a living soul, not man was given a soul. The soul is man himself. The soul can die Eze 18:4. Animals are souls Lev 24:18. The spirit is a lfe force. Before God breathed into man the breath of life he was lifeless. Ec 3:19-21 discusses what happens at deat respection both humans & animals. The spirit or life force goes out, they die. The spirit could be likened to electricity. BBy itsely electricity has no personality, when when it activates a light it glows, when turned off it goes out. So too with the spirit it is the life force in all living creatures . When it goes out the creature dies. The light does not go anywhere it simply ceases to exist.
