In theory, this is true. In practice, when an "accepted" theory is being challenged, the old guard defends it to the point of slandering those that would espouse an alternate theory. Look at the history of relativity and quantum mechanics. These were not dispassion men saying, "OK, you are correct, we accept the new." No, they were fights of immense egos and bitter disputes. Also, new information is sometimes disregarded when it doesn't fit the the current theory, as opposed to disregarding the theory.
Being a creationist means never having to let a silly little thing like evidence change your opinion about something.
Creationist start with the postulates that God created everything and that the Bible is the inerrant word of God, neither of which can be proved by the scientific principle. However, neither can the scientific principle cannot be proved by itself.
I will repeat myself: science is being practiced by fallen man, and will always have presuppositional biases. Anyone claiming to be a dispassionate scientist lies to others and to himself.
dispassion men = dispassionate men
Should read:
However, neither can the scientific principle be proved by itself.
While it is true that it is difficult to present evidence that a problem with a cherished theory exists, if you do so successfully you are a hero and your career is made. So there IS motivation to disprove a theory.
In theory AND practice the “old guard” in science have almost always been either eventually convinced - or ignored and left in obscurity as the “new guard” makes discovery after discovery based upon the new theory that the “old guard” refused to accept.
Creationists start with the postulate that THEY (fallen men all) interpret the Bible absolutely correctly without question and any and all evidence that contradicts this must be explained away, ignored, or the belief of the person who brings the information must be assaulted.
Nothing in science is ever “proved” - it is either well supported by the evidence or it isn’t.
Evolution through natural selection of genetic variation is a theory that is well supported by the evidence and helps to explain and predict data.
