Why do Christians become Christians?

[abaris]

Or would you confess based on the scientific evidence, not trusting your own memory?

There are numerous experiments pointing to eyewitness testimony being unreliable. These can be easily found by doing a google, so I'm not linking to any specific one. Suffice to say that my own memory played tricks on me repeatedly as I found out by talking to people having witnessed the same event. Just to give one tiny example, since it was one of the first major cuts in my life. The death of my first grandmother, when I was but two years old. I remembered correctly that I was dropped off at the house of some friends of my parents, but I was sure, it was adjacent to a certain park. Turned out, I was wrong on that, since 40 years later I talked to the person where I was dropped off and she had lived at an entirely different place at the time. Another memory had interfered, since I very much liked that park where I thought her house was located.
