Life????

Scientifically life does not have a meaning. There is no real purpose or goal that we must achieve in life however We can create our goals like happiness, fame etc,  I know this is really confusing but think about it. Is there anything or anyone that can tell us what we need to do when we are born. Or is the saying "Nature's goal is to reproduce" true?? 
Lets say we believe that and we create lives then what, they create more lives and so on. Is that it?? Is that why we are here?? Is there nothing else that we are meant to achieve?? Well if you think about it, I guess the only goal of life is to survive, you choose the way you want to do it. You decide what you want to do to get the basic necessities in order to survive or maybe live a happy life. But that is it. Again the smae question "Is this all we are supposed to do?"...........
