i don't believe in god, i have some unanswered questions about god

Most people believe in god/s, some are not. Both sides have their reasons to defend their stand. i don't believe in gods. i don't remember whether in my childhood I believed in gods but I went for temple, i studied my religion. questions about god started in my 16th as i remembered i was argued about the god with my family and friends
i had few questions in that age, people who i argued with are try to convince me without answer my questions. after some bad experience i decide not to argue with any one on this, i argued about this with my self, i tried to find logical explanations to prove god is exist and not exists. this increased the number of questions about the god which i couldn't answer and others too.
finally i decided not to believe in god by following reasons or questions
people who believe are also suffer
i don't believe in god but i have nothing less than who believe in god, The poorest 40 percent of the world’s population accounts for 5 percent of global income while The richest 20 percent accounts for three-quarters of world income (http://www.globalissues.org/article/26/poverty-facts-and-stats). why this poorest 40% exists in the world how many of them are not believing in god or how many don't have faith or are these people bad ? or all the richest 5% are believers and blessed. why USA have high quality of life when Africans don't have food and water.

people believe are not following what god asked ?
guess the percentage of the atheist in the world ? 1% may be less than. so most things happens in the world because of 99% theist who believe in god, any religion ask their followers to love all, does it happens ? why even god cant stop his followers from war, kill, rape cheat

stories are unbelievable
i know about Hinduism, Buddhism, Islam and little about Christianity. every religion have a common thing supernatural stories, which don't have any logic on it. from how the world created to sunset and sun rise these religion have stories but these are unbelievable. if people are born again and again according to the most religions, in 1804 world population is 1 billion in 2012 world population reached 12 billions so where are these 11 billions from. where were they in 1804.

if god is so powerful why he need someone to tell about him ? , why god didn't appear to us ? , why selecting few and showing he is existing ?
what is the simple way to make the people believe in the god, simple god appear and tell people believe me i am the god. still i didn't get why god sending someone else to tell that he is exists. why god keeps every thing secret from you ?

contradicts with science and evidence
some people believe in religion and science too, i don't know why they questioned them self about this, i never heard about the creation of dinosaur in any religions but unfortunately skeleton of dinosaur is still exists.

god created man, world, universe, anything, every thing etc, etc, etc but why?
people who believe in god may argue and believe that god created everything, but why he did it ? because of he have power to create something ?. god created the man, women, tree, dinosaur, sky, sun and he is looking at us from somewhere why ?
any body have right answers for my questions ?
