Any derivative principles based upon the laws must be consistent with the inherent laws. These inherent, natural laws cannot be violated. Any apparent violation of these laws is only a display of our lack of understanding of all the laws and is consistent with more complex inherent laws. Life is the product of these inherent natural laws of the universe. That is, due to the properties of matter and energy, life necessarily arose since we exist.
Life can only develop in harmony with the natural laws in the universe.
Life is limited to and governed by these inherent principles since life is a product of the inherent laws and cannot violate them. Therefore, Human existence, thoughts, feelings, etc., are merely the end result of the inherent universal laws and principles of matter, energy flow, chemical reaction, etc. The atheist, therefore, is nothing more than the product of your environment and naturals laws. He is guided and lead by these Laws and react, plot, hope, and will only in agreement with these Laws. Any purpose thus offered is still nothing more than the product of natural Laws of matter, chemistry, and energy flow.
