"Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe?" (49:10)

أَوَلَمْ يَرَ الَّذِينَ كَفَرُوا أَنَّ السَّمَاوَاتِ وَالْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَاهُمَا وَجَعَلْنَا مِنَ الْمَاء كُلَّ شَيْءٍ حَيٍّ أَفَلَا يُؤْمِنُونَ

Subhanallah.
Yet another proof that Allah alone is the author of the Quran, and knows things no human 1400 years ago could have known.

No living being consists entirely of water, nor was created entirely from water. It evolved in water and is still mostly water.
It depends on how you interpret the verse though.
I wonder if tehre is a living creature whose cells contain less than 50% water.

^ Why do you insist on contradicting everything Islaam says?! Even when you know it's true?!

I'm not trying to contradict eevrything Islam says. It says good stuff for the most part. I'm just a bit skeptical about islamic miracles and everything related to them.
I think you know the verse is nothing special, it's just that you're a muslim and want it to be special, but deep inside you know the truth. Does this sound arrogant?

^ Yep it does. 1400 years ago, how would have people known everything was made from water? Unless a supernatural source told them?

It old you everything was not made of water.
Well, there was that greek guy who said it more than a 1000 years earlier.

I understood the verse to mean that ever living thing contains water, which is correct.

"it's just that you're a muslim and want it to be special, but deep inside you know the truth."

Actually, it's more like you're muslim, you read this, and it strengthens your faith. Maybe if you don't believe that islam is the truth it's harder to grasp, or believe.

Water is the most abundant substance in living systems, making up 7o% or more of the weight of most organisms. The first living organisms doubtdless arose in an aqueous environment and the course of evolution has been shaped by the properties of the aqueous medium in which life began. (Lehinger Biochemistry, 4th edition)

I could do with a glass of water right now

The verse doesn't state that everything is made entirely out of water. So I don't see how any of that matters.

You can interpret the verse in many ways. I first saw it quite some time ago and I first thought it says all living things were created from water. It can also refer to living beings containing water, yeah.
The second part was actually a reply to Ahlääm's post which I found a bit arrogant.

that's right, it doesn't. It's possible to intepret it that way though.

so, what do you propose the verse actually says? That every living organism contains a lot of water, that life began in water...?

Well, it could have said "and we made every thing from water", but it specified that it was only living things that were made out of water. Like I said it before, I understood it as saying that every living thing contains water. Looking at it from the other point of view, the question is: Is there a living thing that does not contain water? No. Which proves this verse to be correct, which I find miraculous. :]

A fair view!
I think the author of the Quran knew every living thing, which I guess in his time were animals and plants, required water to survive, so he made the verse about it. It's possible he deducted every living thing therefore contains water. Nothing miraculous in my opinion. He could have also thought every living thing was made from water, which is wrong.

Why is it that every miraculous verse has to be so ambiguous? If it said living beings contain water, lots of it, i'd probably be impressed. I don't mean to harm your religious felings, I think it's great you have reasons to believe, I just don't think the verse should be portryed as scientific.
