And if few things still remain unknown, then that's Okay. Science is unfolding, and we will get answers to those unanswered questions. But then let both the parties abstain from making propaganda of their versions of answers.
I truly appreciate, and liked very much, your analogy of seeing Lord Krishna as "An extraordinary Indian" who was "a warrior, philosopher, musician, statesman, author and a great lover, all rolled into one." Now this is something we can have faith in, without keeping a chance for any doubts by anyone. With this view we don't need to prove that both the legends "physically" existed, and also we will not feel helpless and like 'losing ground under our feet', if the Leftist unite to prove that stories mentioned in The Ramayana & The Mahabharata were "mere" epics.
