that taking the lid of the biscuit tin doesn't actually prove that there arn't any biscuits as that is empirical evidence and doesn't take into account the fact that you might be nuts, blind or suffer from a rare disease that causes you to see chocolate hobnobs as a metalic silver colour that looks exactly like the bottom of a tin.

You can be certified sane, if you were blind you wouldn't see anything and it would therefore be pointless attempting to look, although you do have your senses of smell, touch and taste remaining to ascertain the biscuit which you seem to be forgetting and I would ask you to name the bizarre disease you postulate. In short, your objections don't really cut the mustard.
