'Spirit' is just another way of saying 'alive'.
“Spirit” thus refers to an invisible force (the spark of life) that animates all living creatures.... Similarly, the spirit is the force that brings our body to life. Also, like electricity, the spirit has no feeling and cannot think. It is an impersonal force.
“The dust [of his body] returns to the earth, just as it was, and the spirit returns to the true God who gave it.” Eccl.12:7
the life-force returns to where it came from—God
With you is the source of life; By your light we can see light. Ps.36:9
“the body without spirit [pneuʹma] is dead.” - Jas.2:26
So if science made all the complex parts of a cell as the brochure suggests it would be lifeless without pneuma (the spark of life) from god.
The brochure is typical WT double-speak. Nowhere does it say science might succeed in making a LIVING cell.
