Mix:

Does it make sense to say anything about something that cannot be tested?
If a claim cannot be tested, can it be known to be true or false?
What would evidence of the supernatural look like?
If the supernatural exists, can it be agreed upon what it is like?
If God had a voice (wich I could record), would he still be supernatural? Is he supernatural?
Can everything natural be known?
Can something be principally unknowable and still be natural?
Is everything that exists part of nature?

Reminder:
Do these questions make sense?
