The DNA-double-helix is the most powerful symbol of life. Maybe life on earth.
All living creatures - plants, animals and humans - carry the DNA-double-helix in each cell in their entire body.
What we probably never will know, is if DNA is only an earthly thing, and therefore approx. 4 billion years old, or if DNA is a universal thing, that came to the Earth from outer space.
As long as extra terrestial life hasn't been discovered, we don't know if DNA and the way DNA is built, is common in the whole universe.
We humans ought to celebrate and worship life, and by this, life's symbol, the DNA-double-helix, instead of a cross that symbolizes death.
