Maybe if You Looked Up

They compare us to stars
Each and every one completely unique
Shining bright against the blackness

They tell us that we're all different
And that no one else compares
But riddle me this

If I am a star in the night sky
Could you tell me which?
And, assuming this is so, could you tell me when and how I died?
Because, like a star, I was dead long ago
And the world will only notice many, many years from now
