Ashes to ashes, dust to dust.
As an young adolescent I once asked a brainy college student studying science “Is the so called dust in space a special type? Cosmic dust or something?”
“No, it’s just dust like dust on earth.”
To me that was important because it linked the Bible to the reaches of outer space.
Genesis 2:7
God formed man from the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
We are all stardust.
Just like the dust of the earth? Well if the cosmic rays have been blasting earth dust unhindered....maybe...Earth’s magnetic field protects Earth’s life from cosmic rays and atmospheric stripping solar wind...no protection for dust particles out there...
