i can not understand.. how do the humanity alive without taking something as a goal... it is possible?? really? if it's really possible, i wanna do this!! for example: big cats.. they have a reason to live in wild life.. take a look at the fishes: they everytime have a reason to eat the little one.. we have to tave a reason to live on this wild earth... but why??? because of to be a human... to be a good man in the eyes of God..
