1. We see nothing in nature that is able to create life. If we easily saw the creator of life, scientists would have proclaimed it long ago. Rather, they only have a theory called evolution.
2. We DO see a creator of near life. It is man, himself, who created a lowly form of test-tube life, that probably wasn't really life, but only something that was almost life.
3. Since it has taken much knowledge and effort by man to create something that is almost life (maybe it was life), how much greater is the Creator of true life that exists all around us in nature, in abundance, and is the thing that even makes us the life that we are?
4. Such a Thing that is so extremely knowledgeable and capable as to be able to be the Creator of the REAL life that exists all around us is the Thing that fits our definition of the word "God."
After all, if it takes all man's ingenuity to barely create life or something that simulates life, REAL life must be something that is very difficult to create. We don't see any process whereby life comes about by accident. Rather we see just the opposite; randomness produces disorder. By comparing man's creation against life that exists in nature, we can easily see that the Creator of the life in nature is Great, beyond our knowledge and understanding.
3. Much knowledge? We did it but we didn't know how and why it worked! The conditions we used intentionally occurs naturally really often, they don't need any knowledge at all to exist.
