First of all your claim that Physics can explain almost everything. Except the begining, which you explain away by saying the universe can just pop out of nothing, huh? Allow me to misquote Einstien
* the more we know the more we realize we don't know
*Science is a long way from explaining everything and often times science and technology fail us on a huge level in unforseen ways.* More people are killed each year from superbug infections contracted in hospitals and malpractice than all the people killed by scientology idiots, neglecting their sick.
Now to your point about Jesus picking the wrong century to appear, because he could have come now and , had an interactive website , and appear on the David Letterman show. You admitted you world not trust yourself to believe if Jesus appeared in the sky speaking with a thunderous voice. So how many non-believers would believe a self-proclaimed messiah preforming miracles on late-nite TV? none I suspect.
Which brings us back to Faith. Let me give you two exhamples from the time of Jesus
There were eye-witnesses to Jesus preforming miricles who did not believe. The followers of Jesus came under a death sentence threat. Do not preach that he rose from the dead. Why would they continue to preach under this threat if they knew it was all a sham. And yet they did and the movement spread through the Roman empire like wildfire.
The Roman empire was the begining of modern history as we in the west know it. It was the first time all roads were connected and trade flowed back and forth across half the world. Coincidence?, YOU could say that. I would not. I would call it good timing.
