How Can We Believe ?

I think we have to be honest in everything especially when it is a matter of vital importance namely our belief.  How can we believe that the food will be dropped from heaven just by praying and how can the Red Sea open itself to allow the Israelites to walk across her? How can a virgin conceive and give birth to a baby without any sexual intercourse or artificial impregnation or insemination?  Black is black and white is white. There is no compromise nor logical argument at all no matter whether you are the most notable doctor of philosophy or other topmost scholar. I just cannot make myself  believe in the impossible! When you see so many people are involved in this God business, the believers, the worshippers, the ignominious amount of resources in manpower and others, you would see how much has been wasted in such fruitless pursuit. When we recollect the past dark ages and ancient times, we can understand the value of such beliefs when the knowledge of our world was still minimum . But with the progress with scientific researches and discoveries, it is ridiculous to say that quite a few are still holding the old beliefs on heavenly father etc.  Wake up all men and women, don't waste your lives on such far-fetched and meaningless imaginings or even fantasies. Let us be more realistic and watch our every step to guard against any weaknesses and ignorance. Work hard to make honest living, keep all the rules for good health both spiritually and physically. We don't need a heavenly father to protect us nor is there such a thing as supernatural power or spirit. All those gods and spirits are just imaginations and creations of the so-called prophets etc. Believe in ourselves and be strong!
