Well, no one claims it is impossible. The problem however is how to verify this.
How would you for instance, verify the claim that our universe has been created last Thurday with all our memories, appearance of age, etc.? And how can you tell that the date of creation wasn't instead on Thursday two weeks ago?
This scenario may be true after all but it is simply not falsifiable and therefore it ain't science.
So our universe may or may not be created by a supreme being but the problem is that we cannot tell one way or the other simply because we don't have any other universes (which have been designed resp, not designed) as a reference.
I do not think it would be reasonable to make such a claim, and would certainly not attempt to verify it. I would, on the basis of what I perceive to be factual data, point to artifacts which, to the experience of most observers, date beyond last Thursday.
But you open up a provocative set of questions related to epistemology. When you think about it, if our brains are but chemical reactions produced by natural processes outside of intelligent design, who is to say for sure such a claim is not TRUE?!
I understand that very well, and I can put up with doubts because I have a good many of my own. But I am not about to suggest, as a human, that it is impossible to verify ANYTHING. In saying that, I would also like to hope I am endowed with enough reason to filter out some undoubtedly harmful BS, like "John Kerry for President."
I take that back. I just stated an absolute. Sheez. Everything about all my posts is false.
You are absolutely right here. All we can do is to look at the world that surrounds us, and make judgement calls.
What we have to be sure of is that we do not have an idea of how something happened, before we examine the evidence, for that may taint our conclusion. Now we also know that THIS is highly unlikely, but at least by being AWARE of it, we may then be on guard for it.
Jury selection can play a bIG part in the outcome of a trial.
