It is not a thing, it is an idea. It is a mathematical concept, not a physical object composed of matter and energy and responding to physical law. It only exists in the mind.

Paragraph 2. I have no idea what your're talking about.

Paragraph 3. Yes, Jesus was a person, like you or I, but that is all we know about him. That is, IF he even existed at all. We really don't know for sure. The only evidence of his existence comes from the books that claim he was a divine being, so obviously they can't be considered reliable testimony as to his existence or his attributes.

"Jesus in E = mc^2". I would prefer we not use scripture as reference. It cannot be trusted to be an unbiased source. For one thing, none of the scriptural accounts seems to have been written during his lifetime. We can't even say for sure they were written by anyone who knew him, or even by any of his contemporaries, and none were signed by their authors. Matthew, Mark, Luke and John were designated by tradition as authors of the Gospels long after Jesus' death. I suspect they are highly edited documents compiled from multiple sources. Surely, there must be some other account, some alternative history, some other documentary information about him that could be used to corroborate the scriptures.

Jesus is a lot like God, even if he actually existed, we know absolutely nothing about him, and we shouldn't be talking about him as if we did. It is perfectly legitimate to discuss his philosophy, or his effect on history, but his biography is totally speculative.

But you can't expect anyone to accept your plundering of physics as a source of evidence to justify your faith. If it were that obvious, I'd see it too.
