Some stories are so far fetched, we tend to think they are made up. Of course lots of stories are not entirely true. Sometimes on purpose but usually by accident. Play 'the Chinese whisper game' to test this: come up with a line to say, whisper it into they ear of the person next to you, ask that person to repeat that to the next person and have it repeated a few times. Now imagine there are thousands of people betwoon person number one and the last person and there's a difference of 2000 years between the first and the last whisper. Do you still think everything in the Bible is exactly as it was stated 2000 years ago?
As for me, I don't believe in conspiracie theories. I do however, believe in conspiracies.
