Both my claim and theirs are unsupported by evidence, therefore they are equally valid.
A third argument is that it was because of aliens from the planet Blotrox Prime. But I suppose without evidence we'll just have to accept that all three theories are equally probable.
Interesting how you decided to switch to hyperbole instead of providing evidence for your claim. Backing up your viewpoint would have easily shut me down, putting the ball in my court to do the same. Instead you gave a knee-jerk childish response.
