I will dig up the Roman Empire version of "Media Matters" to meet your request. LOL, you received plenty of historical evidence in that previous thread but since the atheist websites all deny it, so did you. We both know by your above 'request' you are not seeking evidence but subjective proof. And the only way you will be satisfied is if God does drop a call to you, but even then you could write that off as a crank call. Emails can be hoaxes too. So don, the only way to satisfy your curiosity is to have a personal revelation. And even then, since you dismiss the scriptural evidence you won't know how to test such a vision or revelation.
But I do know this...If you seek God with a humble and contrite heart, you will find Him. Call on His Name when He is near and you won't be disappointed. In order to prepare "your field" for sowing you have to do some plowing and He will surely send the rain.
By contemporary evidence, I mean that I would not rule out something modern.
Or something written at that time, that was specific.
An email from G-d today would work. Get right on it, ok?
But something written 30-100 years after the fact? not so much.
Look. I circled 6 random digits from Pi in my CRC.
All I need is an email telling me which ones I picked.
Certainly the Diety will know the right ones.
Of course the odds of getting the right ones, absent a Diety, is 0.1^6 or 0.000001 or one in a million.
It is a simple task. Other things would work too, like unambiguous contemporary evidence.
