Answer:
Use me if you really want to see inside someone
I have six faces but not even one body connected 21 eyes in total but cannot see.
I will disappear every time you say my name.
Though I am dark Adam married me.
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.
It weighs next to nothing but no one can hold it for long. What is it?
