Answer:
I come without being fetched at night, hide away as soon as daylight strikes. Although I may look small, I am much mightier than what you can imagine. What am I?
I am the black child of a white father a wingless bird flying even to the clouds of heaven. I give birth to tears of mourning in pupils that meet me even though there is no cause for grief and at once on my birth I am dissolved into air.
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched especially with a lot of force. I like to be in buildings.
I was was before was was was.
