^^^ So if there's even a microbe, the show's *not* off?
I took Carol's statement to mean that the life-generating effect wouldn't work if there was even microbial life present.
I took it as an either/or extreme.
If there's no life, then the Genesis effect would result in life where none existed before.
If there were even microbes, then it would destroy such life, in favor of it's new matrix.
Genesis either creates life or destroys life, based on the conditions present at detonation. This was my understanding of its function. Or was the lifeless requirement a condition to test the Genesis experiment in a sterile uncontaminated controlled environment?
