two scientific miracles puzzled me?

[truth search]

i think that you are right because there are many scientific errors in the quran.
but the problem that confused me: if mohamed is the only man that observate these two phenomena or not?
because muslims could say that mohamed is the only man who said that the wind have a role in raising clouds and that there no year is rainfull than another  , so, it can't be an observation. because if it is an observation many others will have the same observation.
it's true that we can responding them by proving that there are many scientific errors in the quran.
but if we prove that there are another men that observate these two phenomena, we wil refute their claim completely.
so, i began my research, and i found that the romans philosoves thinks that the "Wind transported water to the clouds":

Better research, after 15 seconds on Google:

https://en.wikipedia.org/wiki/Timeline_o...#Antiquity

Observe discussions in India, 3000 BC, by those who understood, notwithstanding their incorrect idea on how, that the movement of the earth causes wind, which gives rise to clouds.

3000 BC was a very, very long time before Mohammad.

Bullshit busted, Mohammad really wasn't all that special.

i found also that the linga purana (hindu book dated back to 600 C.E ) says:
" after getting the sun light, the water in most of the materials on earth get converted to smoke (vapour) and ascends to sky with the air and is the cause of cloud formation. these clouds cause rainfall under the guidance of lord indra, having thousand eyes".
you can find the text here:

the wiki says:
" Approximately 505,000 km3 (121,000 mi3) of water falls as precipitation each year" 
it's completely false?

I'm at work right now and on my phone typing this so I can't copy and paste all the relevant links easily.

Wikipedia says this is an approximate amount.  So it's not exact.  Also you need to search for how climate has changed of billions of years on earth.  I suspect the rainfall amount of 505000 is an approximate amount since records began but as I said just make your own judgement.

If you look at the earths changes in climate, ice ages, times when the earth was so hot it had no oceans, then it cooled and the atmosphere rained down creating the oceans, heat changes due to global warming, do you think the global amount of rainfall every single year on earth has always been the same?

thank you for the clarification.
