"Star Dust" my answer, becoming one with the universe. They say ashes to ashes, dust to dust so in this theory I go for star dust, float till we stick who know what, when, where or why it is not me in my current format so take it anywhere you want ☺️
I like that idea as well, kind of becoming one with the cosmos we came out of again!
We are but a moment in time, why would we think we are anything more than dust in the cosmos.
