Answer:
My days are numbered. What am I?
I do not contain flesh feather or scales; yet I have fingers and thumbs.
I can wake you up in the morning but I require no electricity or winding.
Weight in my belly trees on my back nails in my ribs feet I do lack.
I am made by nature soft as silk; A puffy cloud white as milk; Snow tops this tropical crop; The dirtiest part of a mop.
I'm a god. I'm a planet. I measure heat.
