Howdy, Aristeo --
As everyone else has pointed out, there's no independent way to verify your claim:
a) that Jesus existed
b) that your specific dates are correct.
However, another portion of your claim is that you received this information from a spirit. Is the spirit willing to give you other information? If that's the case, you might have a testable claim. Check out the Challenge Application board and look at the cases there. If your spirit can provide you with the kinds of information that those claims are claiming, then you can use a similar protocol.
For example, let's say your spirit is willing to provide you with information about what random word a person has pulled out of a box of words (in a different room). Your protocol could be something like this:
Equipment:
100 target words, compiled by you from a standard dictionary, on separate slips of paper, in a box with a coverable hole that's large enough to admit a hand, that has been shaken well by anyone who cares to, so that everyone's satisifed that the contents are scrambled.
Two rooms, separated enough by distance so that the persons inside can't tap, whistle, or otherwise communicate.
A person to pull out the "target word".
You
Two observers -- one with you, one with the "target word" person.
Notepads and pens
Two-way comms -- a radio with CW (morse code) capability, or otherwise some other means of non-verbal communications
Protocol:
The "target word" person sits in one room, you in another. Each of you has a pad of paper & a pen. Your observers have the comms units. The "target word" person pulls a slip of paper out of the box, looks at the word, writes it down on the sheet of paper. The "target word" person's observer will then "buzz" your observer with a single beep to let you know that the word has been drawn. Your observer responds with two beeps ("notification received").
Once you get your beep, you let the spirit tell you what the word was. You write it down. Your observer then sends a single beep back, which is responded to by a double beep. The "target word" person draws another word, and the process is repeated 10 times. The test is a success if you correctly identify the target word 8 out of 10 times.
This is just a re-hash of a protocol that was developed for someone else. The substance of that person's claim (that is, HOW they were receiving the information) was different from yours, but the EFFECT could be the same, if your spirit is willing to provide you with that kind of information.
And this is the kind of test protocol you'll need to develop in order to apply for the JREF prize. You have to be able to demonstrate, under controlled conditions, something paranormal. So you'll have to figure out whether your spirit is willing to provide you with information, and what kind of information, then design a test that demonstrates you couldn't have gotten that information any other way.
Will you be able to do this?
