Where do we draw the line?
Is not life simply an expression of molecular complexity?
It's easy to call an insect alive, but what about a personal computer? They have about the same level of complexity and processing power, yet we consider a computer "nuts and bolts" whereas the insect has some divine force within it that engenders it the label "alive."
The whole idea of life having some "spark" that is not present in other forms of matter is a construction of the human need to feel special, and in no way makes sense in the real world. Life, as in all other things, is a gradient, a slope.
