Intelligent Design

[Simon Moon]

Hey - there's only room for one prophet around here! Work the other side of the street!

In fact, I don't see any value in asking - let alone "demanding" - proof (or even evidence - learn the difference) for unfalsifiable things. I was just going to point out that positing a less-credible and unprovable explanation than rather more mundane yet plausible ones isn't a particularly tenable approach to discerning reality, that's all. Basically, when you hear hoofbeats, first eliminate horses (not literally, in a weird Equus kind of way) before concluding unicorns.

Right, but what happens in instances where you eliminate every known hooved animal? You then have to start to think outside the box, and suppose it may be explained by something we have not yet seen. But yes, I agree we should turn known causes before we turn to things that we don't know can cause it.

But if all known hooved animals are eliminated, the best answer does not then become, "must have been unicorns", by default. The best answer  becomes "we don't know what made the hoofbeat noise, lets find out".

Appealing to the supernatural when you are out of natural answers, is argument from ignorance.
