Nor does it prove yours. They already have credence.
True. It doesn't prove mine. Evidence is required to prove mine. Absence of contrary evidence is not considered evidence in favour. My argument requires other evidence.
If non-existent until proven to exist, they have no credence without evidence.

Just assume that there was no evidence for the latter.

Surely it is safer to assume nothing?
Assuming 'nothing' isn't really possible. Rather, it is assuming multiple possibilities. This includes assuming the possibility which would require evidence to disprove.
AHadley wrote:Disproving something requires evidence by definition. This is how science has always works. The word that sentence should have used is "disregard".
Theories remain theories until they are proven to be factual (they are still considered theories, but remember that gravity is only a theory). In order to prove a theory factual, it must become very widely accepted as truth by a great majority.
Any theory that is able to be disregarded has not yet been proven to be factual by a majority. It is contentious. By default, it is considered incorrect. There are only two positions on a theory. True or false. There is no 'sort-of right', no matter how close it is.
If, on the other hand, evidence were required to prove that this theory was incorrect, it could already be considered factual without the need for evidence in its favour - just the lack of evidence against it. That is just scientifically absurd.

There are plenty of nontheistic religions which this discussion can't take into account, from deism and pandeism to raëlism and scientology.
I don't know anything about the first two. Scientology is just insanity, though.

Assumption (n): a thing that is accepted as true or as certain to happen, without proof.
If you have evidence you are making an estimation.
Semantics. Yeah.

I do not dispute this, but our models for its form and evolution are based on empirical evidence and it is these that led us to our conclusion; it is not, therefore, an assumption.
An estimation, then.

Do remember that this box contains a phial of toxic gas that will be shattered at an unspecified time.
In that case, it becomes impossible to know. There is a physical barrier preventing us from knowing. However, there is an element of certainty. The cat is only either dead or alive. It cannot possibly be anything more than that. Instead of a single answer, there is a dual answer.
This still doesn't mean that the cat is alive and dead at the same time. We just can't possibly know which.
AHadley wrote:Precisely.
Ideally a court would assume neither guilt nor innocence in order to prevent the judgement being clouded by that assumption, but as this thread illustrates people find it difficult to believe nothing.
That ideal is impossible. We're all subjective beings by nature. The next best thing is to assume innocence.
Again, it's not assuming 'nothing', but assuming two possibilities at once, one of which requires evidence to disprove.
