Please don't presuppose me so foolish. Scripture is evidence, so I expect every scoffer to steadfastly maintain it is not.
Sure you can. You can say anything - that's the whole point of denying God in the first place.
Now for the benefit of honest readers, I'll explain a little. Testimony is evidence. One may reject it; one may consider it inconclusive; one may not honestly deny its status. The Bible contains a great deal of testimony.
Isaiah 51 begins "Who hath believed our report, and to whom is the arm of the Lord revealed?" There is no greater question, and the Lord's servants have always known and understood. Scoffers pretend their ways are "new" and "modern" but this is bluff and rubbish.
It is commonly said that testimony is a relatively weak form of evidence, but this contention is obviously bogus. Testimony is the means by which we gain most of the knowledge we possess. Pay attention in everyday life sometime. You either observe something yourself, or you rely upon testimony.
Testimony is the means by which we learn what others have observed.
And now, it is appropriate to remind the readership that we have not observed a solution to the riddle. Faith requires science, and science requires faith.
