As for Dec. 25, there is considerable evidence that Christ was CONCIEVED on the JULIAN 25th (in 6BC) during the Festival of Lights and the Solstice and he was BORN during the Festival of Booths. As for the supposed similarities between Christ and Buddah, there are a great many things attributed to Buddah, most of them show no evidence of having been recorded fewer than a thousand years after his death. Much of this seems to be a case of "Hey, that sounds cool. Let's say that Buddah said and did that." Because there is evidence of Apostles in India and missions quite early in China, I would have to see strong evidence that these things were recorded before 30AD. The most respected scholars keep pushing the NT writings back from hundreds of years after Christ to quite near the time of his Ministry.
