Would that level of evidence allow you to convict someone of murder?
Using your and the jury’s threshhold of proof, no circumstantial evidence could ever convict. A defense theory that aliens were the culprits and ‘staged’ the scene would yield hours of testimony by experts debating the existence of extraterrestrials and their potential for malevolence.
Stupidity combined with arrogance, you are a defense lawyer’s dream juror!
