When I come up against a creationist claiming that a creator can be less complex than it's creation (and therefore more probable), my stock response is something like this:
"Do you REALLY believe that the mere human body is more complex, and so in a sense, more advanced that the glorious creator you propose?"
It's fun to see them furiously backpedal when they are accused (for lack of a better word) of believing that a human is is some way superior to their god
.
As to the definition of complexity, I agree with Leo, there is no standard definition.
I also think a reference point is needed.
A cell is extrememly complex in comparison to the molecules it is made up of, but a person is complex in comparison to that cell.
It doesn't make any sense to me to talk about absolute complexity.

Galileo was a man of science oppressed by the irrational and superstitious. Today, he is used by the irrational and superstitious who claim they are being oppressed by science - Mark Crislip
