A short history about my thoughts

In some days I feel like it nothing in this world have sense, like if the life just was a action of the destiny and I know that it seems very crazy but just think. We work almost everyday for money, this money will be destinated for our food and other topics that are absolutely neccesary for our lifes but we live to die? I don't know we are doing in this planet among this spectacular paradise but just to live and of course the die. We must enjoy our time here? Of course, but just give a reason to believe that the fact that we right now are in this planet aren't random and certainly we have a purpose. I remember when I was just a child and I thought that all world was just the when I lived and other cities near me and no more (I know that it's a little egocentric but i was just a child) so due I was just a child maybe I didn't asked me Why we are here? and why we (for the moment) are alone in the universe. For that moment I went on my life normally with any other question about our existence But when I was a younger I started to search on internet about different topics like that and I liked to read about different scientist theories and no one about our existence but the heyday arrived when I found a photograph called pale blue dot this was one inspiration for me to continue searching and reading about this amazing topic so I continue with this for some weeks later and after....
