two scientific miracles puzzled me?

[paulpablo]

hi everyone, 
muslims claim that there are many scientific miracles in the quran, i found that the most of them are false, but there are two miracles that i didn't found any proof that they are false:
the first is the the aya 48 of the surat 30 that said:
"It is Allah who sends the winds, and they raise the clouds."
the scientist of meteorology until 19th century didn't know that the winds have a role in the raising of clouds, so how mohamed before 1400 years knew that?


the second, mohamed said that: 
"rainfall in one year is no less (in amount) than that falling in another year, it is only allah distributes the rain"
the science proved in our days that 505000 cubic kilometres of water falls as precipitation each year.
how mohamed before 1400 years knew that ?

thank you and i'm sorry if my english is not good.

The second one is wrong.  The earth has changed a lot in the billions of years of it's existence.  There's been ice ages, changes in the suns brightness in relation to the earth.  The formation of oceans on the earth was due enormous amounts of rainfall after the atmosphere began to cool and water could actually exist on earth.  It also says on Wikipedia that rain precipitation is changing globally due to global warming.

2nd point.  There is no scientific proof that I have found that exactly 505000 cubic kilometres of water falls each year.  I've seen on Wikipedia and other sites it says that is an approximate amount  .  The science wouldn't say it was approximate if it was proof that exactly that much falls.  Plus it's approximately dealing with cubic kilometres which isn't small amounts.  And as I said in my previous point I'm nearly certain this is since the existence of weather records or at least since humans have inhabited the Earth which is a miniscule portion of the entire earths history.

3rd point.  It doesn't say which rain, where, or what type of rain.  The science hypothesizes that some planets may have iron rain, some neon rain.  (neon rain or iron rain would be such a fucking cool name for a band, just a thought.)
