True, wine can be a natural occurance..

Everything is just a manipulation of elements.

However, we haven't change fire in anyway...just controlled it. Therefore, not an invention.

Steel does not occur naturally...we must refine and then combine naturally occuring materials to make steel....so it counts. Same goes for concrete.

I am pretty sure you could find some basic steel (iron) in nature.  Man didn't invent steel.

Not everything is a manipulation.  Some inventions are abstract and purely man-made, like time, languages (not speaking, that is natural), religion, etc.

Curiosity- without it we would still be beating each other with sticks and throwing stones...

Is curiosity our invention?  Animals are curious.

Sure man invented steel. No one mines steel, they mine various types of ore...then combine them to make various types of steel. Steel isn't like Gold/Silver/etc which can be mined directly.

Good point...I always think of inventions as 'things'. Language may very well be the best invention.

[NAKID]

But iron isn't steel. Iron is an element (Fe) of steel...

[mitt]

True, steel is a man made object made from naturally occurring elements and processes, and definitely an invention.
