Everything exsists because we want it to. Humans invented numbers, maths. If we weren't here to listen to someone explaining a fibbonacci sequence, the petals would still form, still grow in the same orderly way. Humans invented art, writing. The ideas wouldn't even exist if we weren't here to think or express them.
If art or numbers had not been thought of by the human race, the world would still be here, but in a different form. It exists in the way we want it to. In the way we have created it......yet we spend our lives complaining about what a sucky world we live in. We created our world in its existing form...with rising and falling stock markets; starving people on one side of the world, and food mountains on the other. If enough people want it to change, it will.
