But does this mean we can’t be certain of any scientific conclusion?
I mentioned previously that as predictions are repeatedly confirmed, the likelihood increases that scientists are on the right track. A hypothesis starts out as mere intuition and, as data lines up with expectations, we become more and more certain that the hypothesis is correct, although in science we can never be 100-percent certain. So given any specific question, as science progresses, there is a period of relative uncertainty and a period of relative certainty.
The question we need to ask regarding any specific issue is, at what stage in the process are scientists?
Some will say here that at least as far as evolution is concerned, the theory has definitely passed into the certainty phase. Except that evolution is not one concept that either passes or fails but many different elements that must be evaluated on an individual basis.
