Week #10 What came first the chicken or the need?

 Here is a little playlist for you to feast on Click.

During one of last weeks classes we were learning more our upcoming trip to Paucartambo, out of the blue we stated discussing if the need for something comes before the thing itself, I don't remember how or why we started talking about this but it generated a debate that lasted about 20-30 minutes. I know that this may not be very relevant to the course at first sight, but in this course we need to analyze topics thoroughly and this is a topic that can lead to debates that could last hours, as a matter of fact if we could tackle this question again in class we would definitely spend at least 2 periods on it and we would not get to a concrete answer; I even heard two of the people that were part of the discussion talking about it after class.
The question is be "Does the need for something come from the thing or does a thing come from the need?" I will try to say my own argument. I strongly believe that the need for something comes before the thing itself, I am not saying that everything that exists is created because everyone needed it but it is fair to say that it only takes one person or thing to need it for it to be created, by a thing I mean for example when earth needed a way to purify oxygen trees and plant were created, this example could not be taken seriously because it is a broad statement that cant be used as proof but it is just an example that explains what I am trying to say. Another example that can be used is found in theater, saying a thing comes before a need is like saying that a play comes before a stimulus, you cant write a play out of nothing because nothing from nothing leaves nothing.
An argument used by one of the people in class was that for example people buy laptops because they want then and not because they need them and that people don't need laptops they just want them because they exist, but this is wrong because laptops were created because people needed them people needed a better and faster way of transporting their computer so that is how laptops were created because people needed them. After saying this another thing was said, "I don't need it" and it is true people don't need everything that is created but it only takes one person to need it for it to be created, because nobody says "I have just created this from the top of my head, now I need it" nothing ever has been made just because it is made, people make them because in some way they need them. Sometimes you need something because you want it and that is something that sparked up a little bit of tension "want and need are not the same thing" and that is completely true but when you want something you need that thing, for example I want a new dog and I don't need a new dog, but if I don't get the dog I will have an empty feeling because I don't have what I want so to fill that empty feeling you need a dog.
I will now do something that should never be done when debating but I really think that it fits in with what we are trying to understand, I want to mix religion in this. Religion is something that you cant touch, something that you cant see, it is something that some people feel; I feel that religion is a way for ancient people to explain what was going on around them and what everything meant, for example, why do we fall in love? we fall in love because Aphrodite created love. And why do I like that girl? you like that girl because you are under Eros' spell, and so on and so forth. Ancient people, in this case the Greeks needed religion to explain everything and that is why they created religion because they needed it.
I would like to continue discussing this but there is no one to give me an opposite opinion on this. But can things appear from nothing?
