Why Deism?

Since I left Islam, I am being constantly asked by my atheist friends why I have chosen Deism and why not Atheism or Agnosticism. Well, I have to confess that I am a highly spiritual person. I have always had a very strong belief in God. This is partly because I believe science will not answer all my questions. Religion is ridiculous but so is the idea of existence of something from nothing. I am not just a random collection of molecules, my emotions might be due to chemicals in my brain, my feelings might be result of physical stimuli, but there is more than that. I am creature of love and hate, compassion and corruption. I am creative, I am destructive, I am evil and I am good, I am inexplicable and incomprehensible, there is a conscience, there is a ghost in the machine.
Deism is a concept that holds a rational view of world, with no need of any organized religion. But this rational approach of Deism has a room for an intelligent supreme being. The universe is like a clock wound up by the supreme being, has a pre-specified time duration after which it will ultimately stop and die. You can call that intelligent being God, Krishna, Buddha or Spaghetti Monster if you want; all is fine. But one has to admit that there is something out there that started all this. Most probably, the intelligent being we are talking about is as powerless as any of us. For if he were powerful with a tiny bit of conscience, he would have done something about the filth, famine and disasters in this world. This gives me a sneaky idea that god is probably a nerdy scientist. The universe is but an unintended unsustainable consequence of his uncontrolled experiments that went horribly wrong. And since he cannot control it, he has no choice but to sit back and watch the universe run its course.
Coming back to the topic, I am not a hypocrite to suggest that Deism is the answer to the mystery of universe. I believe that the riddle of existence is too big to have a single path to the ultimate truth. Rationally thinking, you can not be sure with complete certainty of any belief that you hold whether it is Atheism, Agnosticism or Deism. Every single one of these beliefs has justified criticisms. But no matter what beliefs we hold, we should and must have a unique philosophy on the purpose of life. The purpose that became the reason we are here today, the reason we can talk, think and act. The purpose of life is nothing but to evolve… morally, ethically and intellectually. Thousands, maybe millions of species have died so that we could evolve and exist… let us not their sacrifices go to waste.
