HELP with CHRISTIANITY!?! I have some questions..confused. HELP. thanks :)?

Hi there..Well first of all allot of people to day deal with parents leaving there kids when they are young mostly fathers and then the children see them years later that's the norm in this day and age and i believe that fathers run away because they are scared of the fact on how to deal with kids and raising them and when the reality hits them they just run away...When we look at he world today and see what's going on such as the suffering,war,violence,crime and murder and the list goes on it easy for man to say were is God and why does he not fix this mess..The world is the way it is because of sin the fall of man not God everyone wants to blame God and man cannot seem to understand that so people become Atheist because they conclude if God was real he would fix this earth,Sin Separated man from God and the Bible says there is a day appointed by the man Jesus Christ were God is going to Judge this earth or clean it of Sin and Wickedness...The Big Bang Theory is a Theory were man tries to give us an understanding of how the earth started or came into being but was man there when the earth was being formed??In the book of Job God tested Job during a period of his life and during that time Job challenged God and after the test was over God answered Job and said were where you when i laid the foundation of the earth??were where you when i called it into being?? were where you when i made the oceans?? the bible says that man is but dust for from dust he is made and dust he shall return..What does created man really know about a universe?? Does man know the course of the future? Could man change the course of time? Jesus says in Matthew that God knows the number of hair on our head..Could man count the grains of sand on the beach??..Should we trust man or God?? man discovered allot but who gives man the ability to discover? why does humans look for answers? why do we search for what we really don't understand?? No scientist has ever fully concluded they keep looking for answers to there conclusion...
