First off, I am an atheist, so I am not going to tell Christians what they should or shouldn’t believe. That’s up to them. If you choose to only accept evidence that supports your interpretation of the Bible, then go for it. As you say, we all make choices.
I would also like to add that not everything is meant to be literal. Jesus spoke in parables, and it would be strange to ignore the lesson trying to be taught simply because the events in the parable may not have actually happened. Truth, wisdom, and knowledge can be derived from myths and fables, and this was common practice in ancient times.
There can be questions of evidence, and there can also be questions of one’s commitments to a preconceived conclusion.
