Description

After stretching this, I just thought: "shell on the beach"...

Next time you're walking along the beach, feeling the pebbles and grit between your toes... looking down to find a shell opened up towards you, you might think: I'm looking back in time:

In this place, life emerged, grew, thrived and then moved on, perhaps to feed new life, definitely having an impact on its surroundings.

Then you might look up, if its night and dark around you, you might see the Teapot. Look deeply enough and with some assistance: you might see #M8, the #LagoonNebula.

Now you're looking much farther back in time, seeing the stars born of their "shell" of Hydrogen and dust, fusing the heavier elements, forming the stuff of us, the beach you stand on and of course: the shell you've been staring at.
