But there is no evidence of this happening.

In which case you can arbitrarily choose what is true and what is not, with no evidence.

For example:

'Harry potter does some things which are impossible, he uses magic'.

Did this really happen?

How do you differentiate between the two?

Or as a more direct example, any ancient text which contains things which we know to be impossible, but were helped with the power of a god. There are many stories from many different cultures.

How do you tell which one is true and which is not with no evidence of any being true?
