Sign of God

In so many places in the Quran God says to look at the heavens and the earth, because there are signs, “Do they not look at the sky above them? - How We have made it and adorned it, and there are no flaws in it?” (Quran chapter 50 verse 6) if we observe the sky, we see so many layers; Ozone layer, troposphere, mesosphere and so on, each having unique function of there own, for mankind to survive on this planet,
In the Quran God Almighty says about the rain “Do ye bring it down (in rain) from the cloud or do We? Were it Our Will, We could make it salt (and unpalatable): then why do ye not give thanks?” (Quran chapter 56 verse 69-70) also not only that the rain is collected in rivers for agriculture and other benefits, what if there was no impermeable stratum? (Meaning if all water would sink to the earth), God Almighty says “Say: Have ye thought: If (all) your water were to disappear into the earth, who then could bring you gushing water?” (Quran chapter 67 verse 30)
We find so many delicious fruits and vegetables in various colors, with different tastes, A blessing from God and He says: “It is He Who sendeth down rain from the skies: with it We produce vegetation of all kinds: from some We produce green (crops), out of which We produce grain, heaped up (at harvest); out of the date-palm and its sheaths (or spathes) (come) clusters of dates hanging low and near: and (then there are) gardens of grapes, and olives, and pomegranates, each similar (in kind) yet different (in variety): when they begin to bear fruit, feast your eyes with the fruit and the ripeness thereof. Behold! in these things there are signs for people who believe.” (Quran chapter 6 verse 99)
If we study the sea and why huge ships float, we know that there is a force called buoyancy force which keeps the ships floated on the sea, so who made this law and subjected this force and why? In the Quran it states: “Your Lord is He That maketh the Ship go smoothly for you through the sea, in order that ye may seek of his Bounty. For he is unto you most Merciful.” (Quran chapter 17 verse 66)
There is a blessing that we enjoy always from the time of our birth yet never ponder upon which is breathing, if we were not able to breath for 3-5 min, death would be the result, but we don’t have to worry about that, since it is involuntary, a blessing from God Almighty, how hard it will be if we had to take on our own every single breath. Lets look at our fingers, how hard it will be if we don’t even have one of them, and how hard it will be if they all were the same size, in the Quran Almighty Allah says in soorah An-Nahl chapter 16 "If ye would count up the favors of Allah, never would ye be able to number them: for Allah is Oft-Forgiving, Most Merciful". Why is it that many people don’t think about all this blessing? and God says in soorath Ar-Rahman so many times "Then which of the favors of your lord will you deny" I just said some of the few blessing we have, if you read the Quran, observe and think you can find many.
“Behold! in the creation of the heavens and the earth; in the alternation of the night and the day; in the sailing of the ships through the ocean for the profit of mankind; in the rain which Allah Sends down from the skies, and the life which He gives therewith to an earth that is dead; in the beasts of all kinds that He scatters through the earth; in the change of the winds, and the clouds which they Trail like their slaves between the sky and the earth;- (Here) indeed are Signs for a people that are wise.”(Quran chapter 2 verse 164)
