what is it that i can give up and you dont....

if life was built on bricks and then if we call it does exist then we have something concrete to talk about....but life is not like that its just a fool's paradise where no one is sure that what it is and we are all searching for the reason that why we are all created for...if everything else is myth then we are not left with any logic to evident anything but sth which leads us to questions and those are still unanswered,.....so life is nuthing but an unsolved query..
