The word (Sea or Water) mentioned 32 times, and the word (Landmass) mentioned 13 times in the Holy Qur'an, if we add them together we will get 45.

• By finding the percentage of the number of the word (Sea) to the total number of the words (Sea and Landmass) we will have: 
                           (32/45)x100% = 71.11111111111%

• By finding the percentage of the number of the word (Landmass) to the total number of the words (Sea and Landmass) we will have: 
                           (13/45)x100% = 28.88888888889%

We will find what Allah (swt) said in His Holy Book 14 centaury ago that the ratio of water on earth is 71.11111111111%, and the ratio of landmass is 28.88888888889%,
add them together and you will get 100%, and these are the real ratios of the Water and landmass on earth.

So what do you think? Could it be a Chance?!
Who do you think taught prophet Muhammad all of these?

I am just telling you that "Nor does he say (aught) of (his own) Desire", what you have read is a small part of the Numeric Miracles of the Holy Qur'an, there are big volumes about the miracles of the Qur'an ...
