Here are some 'truths':
Scientific: "The geologic record has no indication of a massive world wide flood in 6000BC"
Faith: "The world was covered with water in 6000BC. It went away leaving no trace in the geologic record"
Faith in science: "Every event has a scientific explanation"
The 'scientific' truth is consistent with either of the 'faith' based truths and does not provide a basis to choose between them. You always have to take something on faith if you want to claim to have the 'ultimate' truth.
