Stephen Schwartz - Spark of Creation (Reprise) lyrics

[EVE] I feel a coldness in the pit of my stomach I feel a watchfulness in back of my eyes I carry a load of heavy forboding I cannot explain My boys are healthy, they grow bigger and stronger No sign of trouble, but I recognize The heat and hunger of when I was younger I see it now in Cain I used to think it was the spark of creation Was it just a defect in me? A flaw in my nature And now look what I've done I've pa**ed it to my son This wild inclination Is it the spark of creation?
