That's a great point, Fran!

The famoused picture of Jesus was made by Michel Angelo who lived about 400 years ago. It's well known that he made a picture of himself. So, Jesus looks like Michel Angelo since 400 years...*SSS*

Some other points are:
1. Are the people in this house extremely evil, or why does the oil appear in this house only?
2. What kind of a God should it be that sends his son to teach the humans and then let them killed by humans? So, the roman imperium was stronger than God?
I don't believe that Jesus was really the son of the Creator. He was a normal human with a high level of perception. Someone like a buddha! You all can reach this level if you really live in humbleness!
3. Why does it started 10 years ago? We all know that the problems in our world started much earlier. I knew it as a small child that the world will die in agony in the near future if we do not change us (especially the big bosses!). So, am I a son of our God because I knew it earlier than the oil coming out of a picture? Nope, I'm not!

Well, the point is: Let a team of scientists into that house and explore the secret and in a few months or years you'll have an exact answer to that phenomenon.
Or you can torment the owner of the picture until he reveals his secret for you...

I guess it's something like it was on other madonna's figurines and so on. I remember on an explanation about that phenomenon. I think it was the fact of two different kind of woods that was used for the figurine. So, a special air condition could cause the madonna figurine to cry out some tears from its eyes. Wow, what a phenomenon...

Or do you remember on candles which lightend up by no fire...whoooo, how magically...
I will never understand why some people are using such cheap tricks to catch the souls of putative unbelievers. If I don't visit a church then this won't mind that I'm an unbeliever.
I don't need an argument for God's existence because I can see it every second in my life. Where can I see it? Everywhere around!!!
The universe is a miracle.
Life is a miracle.
Birth and death are miracles.
Music is a miracle.
Colours are a miracle.
Every atom is a miracle.
All what we're doing with those miracles are also miracles.

Oh, and by the way, God didn't banish us out from the paradies. The truth is: we're still living in the paradies but we're going to distruct it totally...

There's always a scientific explanation for all phenomenons you can see. We've got the gift of experiencing - let's try to explain those phenomenons!!!
