Answer:
I am the third from a sparkle bright, I thrive throughout the day and night. Deep in the path of a cows white drink. I've had thousands of millions of years to think. But one of my creatures is killing me. And so the question I ask to thee, is
Only two backbones and thousands of ribs.
The sharp slim blade, that cuts the wind.
This is in a realm of true and in a realm false, but you experience me as you turn and toss.
There is a creature of God whose body is hardอพ it does not wish to eat unless you strike its head.
If itโs information you seek, come and see me. If itโs pairs of letters you need, I have consecutively three. What am I?
