Fifth: Common sense is not evidence. Common sense is what leads one to conclude things like "bowling balls are heavier, so they must fall faster than pencils." If we don't have the evidence to show that what we're claiming is true, then the claim doesn't mean anything. You're making the claim "these things couldn't logically be true," so you're responsible for providing evidence that illustrates a logical contradiction. I'm saying "there's not enough evidence to claim this," so I'm not required to provide evidence of a lack of evidence, since that would be absurd. I'm only providing enough to counter your own, and show that things are possible where you claim them not to be.
