Sometimes I have trouble understanding you Luis. Let us be specific. I am a staunch supporter of evolution, my evidence stands on its own. However I am constantly told on these boards by creationists that the evidence doesn't work to prove evolution. I am not told how it doesn't work just that there are holes or that it doesn't explain the complexity. Go saunter into the evo threads, I've seen you there before. You must understand what I am talking about.
Yes, I do. It is incredible how far they will go in their denial.
However, there is a world of difference between denying evolution (which is deep denial and goes against tons of evidence) and denying the existence of deities (which are basically evidenced only by the belief itself).
People
are entitled to simply disbelieve in however many deities they see fit. And believe them back into existence if they want. In a whim, if it comes to that.
There is no contradiction whatsoever in so doing. As a matter of fact, there is no way for any beliefs about deities to be insufficiently supported, because deities are such arbitrary concepts to begin with.
Are you trying to tell me that it is valid to simply say "evolution does not exist" and to say when asked that the evidence doesn't support it, and the person that says such does not carry the burden of showing how the evidence is flawed?
No. Of course not.
Now let's try abstractly, you agree that if someone makes a claim they carry the burden of proving that claim? Now after they give their evidence, if a person asserts that the evidence is not valid, the person who is now making a claim is the person claiming "the evidence is not valid." Thus this person now has the burden of proof.
That is valid in most situations. It is definitely not the case with claims of the existence of deities, though. Those are inherently one-sided, and so is the burden of proof.
Assuming, of course, that the theists care about proof in the first place, which they probably should not, since that would have little use for it. There is no point in attempting to convince disbelievers, and therefore less use for proof.
