Obviously this looks very bad but you don't seriously think it constitutes evidence?
Are any of the facts in this hypothetical "evidence"? With the knowledge of the truth (that the kid ate the cookies), it's clear these are all relevant pieces of evidence. If we take knowledge of the truth out of the equation, would these facts still be evidence? Unambiguously they would.
And incidentally you can be convicted in a court of law purely on circumstantial evidence, and that's the place in society where we have the highest standard of proof. The evidence all being circumstantial is not a gotcha.
