One can believe in God and Jesus Christ very well without that. There are many examples. Then you believe an untruth. Rabbits do not chew the cud. The Bible gives three different accounts.
Wise men come 'from the east to Jerusalem'.
If they did see a star in the east then they would have traveled eastwards. Jerusalem is westwards. Now, many verses can be explained very well but the point is that they have to be explained. I find the whole concept of a literal reading of the Bible functionally useless. We struggle with explanations and once we touch the Bible, the question of what it means is everybody's guess.
