I feel we've just rediscovered why appeals to grammar[0] don't actually solve much of anything. (Not saying you're appealing to grammar, just that grammar is generally not that useful for discerning... anything really.)

Anyway, to be a bit more substantive: What really baked my noodle when I was younger is the fact that the seasons and the night/day cycle are much more disconnected than it appears when you live on Earth. Of course, it makes sense when you understand the tilt/rotation thing, but still... it really weirds me out sometimes.

[0] English in this case, but any language, really.
