Eye witnesses reports versus angel revelation

About 5 years ago, I have a discussion with a colleague about  an accident or incident and how eye witnesses gave written reports  and later about 500 years later came a man who said he has met with an angel and the "angel" revealed to him a new written report that is very different from the earlier eye witnesses reports.
So who do you trust? The eye witnesses report or the reports that came 500 later not from any eye witnesses but based on the person encounter with a so call angel, He could be an encounter with the devil.

In the same discussion, he said ,"Who is cleaner? A person who takes bath 5 times a day or a person who takes bath only once a week? I thought for a while and answer him, depend on what types of water he is using? Whether he is using dirty water or clean water. If the person who takes bath 5 times a day using dirty water while the other person use clean water once a week, I think the "once a week" person is cleaner.
