How do I know the things I know?

[Akincana Krishna dasa]

Where's the evidence for God?

Apparently there is none. At least, none of his alleged followers has ever presented anything worth more than a fart in a hurricane.

I don't know, I think a fart in hurricane might prove that God exists. Lets say it smelled really bad. Wouldn't that convince you?

You skipped to the second part of my question. First is: How do you know anything?
