"If a tree falls in the forest and there is no one or no thing close enough to hear it does it make a noise"? Science
tells us that it does not. Let's not argue with science on this on.
To prove to you that there is a God you would have to first, believe that the universe does in fact exist. Then you would have to believe that it is not possible for it to have always existed. Therefore, you would concur with other thinking people on this planet that it was created. If it's true that the universe does exist and that it came into existence through some process of creation then it would have to have a creator. Some people believe that God and the Creator are one and the same and that He alone spoke the universe into existence. Others believe that the universe was created with the explosion of a primeval atom, (atom: the smallest particle of a chemical element) or the Big Bang 10 to 20 billion years ago. Either way, I think we all, in one way or another, agree that this universe was in fact created.
Now, if God created the universe then it's settled even if no one can explain how, when or why. If the universe was created by the Big Bang then you have to explain where the atom came from and what cause it to explode. It's not rational to assume that the atom had always existed but not the universe and that the explosion was caused by accident. Okay, even if it were caused by accident then what caused the accident? They don't just happen you know. Was the Big Bang Theory so named because of the loud noise it made? If there were no one or no thing close enough to hear it, then, how could it have made a noise? If there was no noise then why is it called a bang.
Okay, so you're not convinced and that's alright too, so long as you accept the fact that the universe was created and things created have a creator. I will accept that the Big Bang accident is your creator and therefore your god.
