Claiming to Already Know Everything
Creationists often accuse scientists of taking on faith that they already know everything and that they take on faith that nothing exists outside current scientific knowledge. In the next breath, they chastise scientists for changing their minds about the big bang when new data came in.
Scientists merely claim that science reflects the best explanation we have come up with given the current evidence. It is subject to change with new evidence or a better idea.
Creationists are the ones who claim they have known everything there was to know for 4000 years and have not changed that view one iota since, despite ample evidence they are wrong.
Scientists looking back over the decades, can see all manner of new discoveries. They fully expect an accelerating rate of discovery in the coming decades. This is hardly a belief that all is already known.~ Roedy (1948-02-04 age:69)
