this is to answer atheistdave's post, first of all i'm a muslim, and i can give you a billion quotes from the qur'an which prove the existence of god. the qur'an was revealed 14 centuries ago, yet many of its statements are now being proven right, it had already stated the big bang, the expansion of the universe, the pairs in creation, human creation, etc; etc; Either we had a beginning or we didn't, If we do exist, there are only two possible explanations as to how our existence came to be. Either we had a beginning or we did not have a beginning. The Bible says, "In the beginning God created the heaven and the earth" (Genesis 1 :1). The atheist has always maintained that there was no beginning. The idea is that matter has always existed in the form of either matter or energy; and all that has happened is that matter has been changed from form to form, but it has always been. The "Humanist Manifesto"says, "Matter is self-existing and not created," and that is a concise statement of the atheist's belief. I've given examples of many of the above from the qur'an already, so i'm going to switch to the second law of thermodynamics, In any closed system, things tend to become disordered. If an automobile is driven for years and years without repair, for example, it will become so disordered that it would not run any more. Getting old is simple conformity to the second law of thermodynamics. In space, things get old. Astronomers refer to the aging process as heat death. If the cosmos is "everything that ever was or is or ever will be," nothing could be added to it to improve its order or repair it. Even a universe that expands and collapses and expands again forever would die because it would lose light and heat each time it expanded and rebounded. The atheist's assertion that matter/energy is eternal is scientifically wrong. The biblical and qur'anic assertion that there was a beginning and an end is scientifically correct.
Now you asked me what i have seen to have such a strong belief in god, I haven't seen god of of course, but i have felt him through prayers, daily life, etc; How would you explain for mysterious phenomenon such as answered prayers? You think people are crazy when they tell you that they have seen spirits or other phenomenon, well if you told me something similar two to three years ago, i would laugh at you, but now I would understand, they aren't hallucinations, they're real, i wouldn't like to get into my personal experience however. But I have full belief in god.
