Not much it seems.
Spread a rumour that moisture is seen anywhere near a religious idol and without any examination for leaks in the roof, high levels of humidity, sudden changes in temperature or downright fraud by people ready to fleece the gullible pilgrims - you have a miracle.
To the best of my knowledge none of these 'crying statues' has ever stood up to forensic examination.
And, here's the thing, if there was a god, why do you imagine they would stoop and bother with such a ridiculous fairground stunt?
For a supreme being what would be the purpose?
The very triviality and lack of imagination suggests it could only be man made.
