When the existence of God came into question it is imperative to know if we are referring to the same meaning of the word. Because some refer to "God" as the Source of our existence or The Creator or simply The Maker.Others have different notions. If that is your meaning of God then I believe that such a person exists. Simply because we are here on this planet, it is very impossible to think that we simply existed as human beings from the very beginning without a source.It would be very absurd to logic and systematic thinking into believing that we simply came to be without a "Maker" or a "Creator". Everything that we ever did as humans has a beginning from the minute details up to engineering and the highest technology ever invented.
Our history as humans forces us to believe that there is at least a beginning to many things here on earth especially those that we invented ourselves and nothing manmade could ever be called "manmade" without a man to create, invent or make it. Therefore, human history and present day-to-day experiences forces us to a conclusion that there is a Great Maker of at least the human species because we must have a beginning in order to exist. To conclude otherwise is to object to our own human-technology-and-invention experiences and history where we are the maker and creator of things so to speak.
So this is what i think.
I do not believe in a "God" because tradition or anybody else taught me. I believe in a Creator-God. I'm force to believe because of our own experiences as a human race and our capacity to invent things and because of our ingenuity.It would be illogical if we just came to be, as genius as we are, without someone who invented us and made us.
It is hard for us to believe that an aircraft, as sophisticated as it is, has to be without an inventor or someone who made it. How then could we easily believed that we as sophisticated, gene-imbedded human beings, came to be without someone, more intelligent than we are, who made us from the very beginning? It simply is not logical and it defies reason. Logic and reason forces me to believe in a Creator-God.
