How do you debunk conspiracy theories based on coincidence?

[deusex]

So today I came across this hilarious piece on Facebook.

According to the link if you can't see it, the Hanuman Chalisa calculates the actual distance to the sun by 1 Yuga x 1 Sahsra x 1 Yojana = 12000 x 1000 x 8 = 96,000,000 miles = 153,600,000 km which is the approximate Earth-Sun distance.
Therefore whoever wrote the Hanuman Chalisa was an accomplished astronomer. How do you debunk stuff like this (Apart from the fact that it's quite possible to calculate the distance empirically by calculating the angle between planets and ancient Greeks and others already did)

Is there a logical fallacy that is applicable here? Can you call this a case of cum hoc, ergo propter hoc?

most of such coincidence are actually quack. all you need to do is work up the facts. and this one is pretty nonsense.

[openminded]

Well,
Mathematically, the unit of the quantity 96,000,000 should be year.miles (Note 1 yuga = 12000 years, and 1 yojana = 8 miles. So the multiplication cannot have unit of miles alone.)

Moreover, the poster in the link given above claims that NASA has stated this to be the exact distance between the Earth and the Sun. The average distance measured (and provided on NASA website) is actually 149,600,000 Km. Even though the difference between the two figures is pretty small (2.67%), you cannot term this as "exactly the same distance".

Inference: This is not even a coincidence - it is just a post-hoc number jumble.
