The most logical thing to do in making a decision of whether this planet was created by a God or not would be to look at the odds and make your decision. After all, that is what we base many of our decisions on in our everyday life. If we first look at if a creator didnt exist, everything that is here today must of happened by chance, therefore there must be a non supernatural answer for everything that happened. First, one of the most fundamental laws of science is matter cannot be created or destroyed. This presents a huge problem for an athiest in trying to answer the beginning of everything, because being men of science they must obey all laws of science. It is also a valid question, "Well, where did God come from?". However, the difference here is God is not a scientific being. He is believed to be a supernatural. Nothing to do with this world or time.
Secondly, could everything happen by chance. It is very unlikly. What are the odds of our sun and the planet earth exploding out of a huge flaming mass of nothing and stopping within perfect distance of each other. A thousand miles closer and we would be toast and a thousand miles futher we would be frozen, and a thousand miles in the universe is like one thousandth of a point on a needle. Also how can abiogenisis be explained. Those are only a few of thousands of questions that must be added into the odds of life without a creator. Although it is not possible for me to give exact odds any logical person can see that these odds would be easily into the trillions if not far beyond.
So what about odds of a creator. You cant really place odds on that. Maybe 0-1. Either a God exsist or doesnt. Its as easy as that.
I am a man of logic. I dont bet agianst the odds and neither does 95% of the world. So if you have disbief in a creator, you are one of the smallest minorities out there.
