You don't have to move the goal posts when abiogenesis has never been a part of the theory of evolution. It is fundie creationists that keep insisting that it is without one bit of evidence to show. What do they call it when someone says an untruth over and over and over, even when they have been told it is incorrect.<quoted text> I think at one stage, the ToE tied itself to abiogenesis "but NOT anymore" they say. And I suppose if a Creationist like myself tries arguing another point, you Evos will say "Ah, but Evolution doesn't have anything to do with that either". You Evos are constantly shifting the goalposts that I think one day, you'll end up confusing yourselves!! Creation - like God - stays constant. It never changes. That way the Creos such as myself, at least have a point of reference. On your second point, if the humans didn't plant them, who did??
Creationism is sustained by dogma and worship of the Bible over God. You have faith and little more. Science has facts. I consider them to be a firm enough point of reference, that we have medicine, computers, cars, food.
