No God = No Purpose

First of all, I would like to say, that you present a great argument. However your arguments are based on individual's purpose in earthly matter. You have to realize that live is only temporarily and that we don't remain on this earth for the rest of time. I understand how you said that a scientist purpose in life on earth is to research and discover medical cures, or a philanthropist would help the poor and the needy, and that a father would raise his kids. But these purposes are for individuals in their lives and don't exceed that. However the scientist, the philanthropist and the father all together have a greater purpose for living than their jobs and responsibility. One that is bigger and exceeds a temporal life on earth. What I am trying to say is that each and every person in society has their own purpose for doing what they do, not necessarily for living, and it doesn't exceed the temporal life on earth. However humanity as whole has a greater purpose, one which is superior and one which provides a reason for us being here in the first place. Why would we live and die without a reason behind this all? To think that live just came about in chance would be illogical. That we live and die and that is it, I feel that is very ignorant and closed minded to the truth, that there has to be a creator of a creation. That which is god. How can man not realize his true purpose in live when there is so much evidence to present it? The atheist may say ‘'well there is no god', or simple not care about god, since he can't see him or feel him, worrying about the afterlife seems stupid to him or it simple doesn't fit in his lifestyle. I think it all comes down to first believing there is a god, then one truly has to realize live isn't just living and dying. One will realize there is a reason for why humanity was created in the first place. The Quran present very clear evidence on all aspects of life. 1,000 or more verses relate to man and his surroundings, and it's one miraculous aspect of the Quran. This is because the Quran was revealed more than 14 Centuries ago, with many of the scientific facts, at a time when people had no knowledge whatsoever of such facts. I have chosen two verses that can testify to the miraculous nature of the Quran from a scientific point of view. The creation of the universe is explained by astrophysicists in a widely accepted phenomenon, popularly known as the "Big Bang." The Quran contains the following verse, regarding the origin of the universe: Have those who disbelieved not considered that the heavens and the earth were (once) a joined entity, and then we separated them and made from water every living thing? Then will they not believe? (Quran, 21:30) Scientists say that before the galaxies in the universe were formed, celestial matter was initially in the form of gaseous matter. In short, huge gaseous matter or clouds were present before the formation of the galaxies. To describe initial celestial matter, the word "smoke" is more appropriate than gas. The following Quranic verse refers to this state of the universe by the word dukhan which means smoke:Then He turned to the heaven when it was smoke... (Quran, 41:11) Again, this fact is a corollary to the "Big Bang" and was not known to mankind during the time of the Prophet Muhammad. What then, could have been the source of this knowledge? God and no one but God. The reason god created man, it that man be his trustee on earth (Quran 2:30). Mankind's basic trust, our responsibility, is to believe in and worship Allah: And I did not create the Jinn and mankind except to worship me. (Quran, 51:56-58) As harsh as it may sound, life without the believe in god has no purpose at all. And there are very clear evidence stating the existence of god. Without all this, we only have our little purposes which don't exceed this life on earth. So what is the point of living then, if it just ends without ever having a purpose for it starting.
