I'm sorry, you have totally contradicted yourself.
'Without evidence you just cannot know can you?' I did not say the evidence does not exist.
Not too long ago it became known that an innocent man went to jail for 25 years or so. There existed evidence at the time of his conviction to exonerate him only that they refused to look at it because they were convinced that the man was guilty. When they finally decided to measure the evidence 25 years later, they saw his innocence. -Not to say that the disgraced ones that suppressed the evidence continued to advocate guilt inspite of the facts. The evidence existed had they wanted to look.
