I don't think anyone is going to be able to come up with a real response that defies this.  There will be a smattering of conspiracy theories though.  I have seen narratives explaining contraction and explanation of the celestial bodies as well as their movement through the sky in circles.  You may also get flight time charts comparing the flight times between cites of the same distance throughout the world that mismatch taking no account for aircraft type, common local weather or flight practices in the region.  Be prepared to laugh, try not to insult them .  Good job!
