Answer 1

You can’t prove that something doesn’t exist. I challenge you to prove that satanist unicorns don’t exist. You searched them really hard and don’t find them ? Search harder, you might have missed it.

When you test a hypothesis hard enough, you can affirm that it seems to be quite close to the reality, your hypothesis just became a theory. That means that until proved wrong, unicorns don’t exist.
