Difficult
The hardest questions in history are plentiful. One, however never seems to be resolved and is a question scholars world wide have talked about. That question is asked in many different ways, but it all boils down to "What was the cause of the fall of the ancient Roman Empire?" Certainly there are many other difficult questions, but this one is certainly one of the most difficult to answer.

The answer to this question involves a paradox since you are talking about complexity, any object one might name would be less complex than making the sum of 2 of them, or making however many then connecting them, so to answer your question it is the most difficult man made thing that has been made as of today; the most complicated collaboration of complex things of course being this right here: the internet. Sincerely the answer to your question.
