1. To my knowledge, Occam's razor assumes a negative is always true unless its corresponding positive can be proven. But how does it deal with (or is it even applicable at all?) with statements/announcements? Are all statements/announcements assumed to be genuine unless contradicted? Or the opposite?
For example, say NASA says that aliens exist. Do we assume this is true or false, if no evidence is provided, according to Occam's razor?
2. Since it always assumes that something "does not exist", or "has not occurred", unless there is any evidence, how does it deal with situations where something could have easily occurred or not occurred, but we can't tell for sure what specifically happened?
Example, Mark wakes up and his parents go to work. In the evening, his parents come back home, and don't know if Mark ate anything that day or not (but easily could have) before they ask him. Does Occam's razor by default assume that he did not eat anything?
That's what I would assume, but it doesn't seem logical.
Or is Occam's razor not applicable in such a situation at all?
Thank you.
