George H. Smith
"It is not my purpose to convert people to atheism...but to demonstrate that the belief in God is irrational to the point of absurdity. If a person wishes to continue believing in a god, that is his prerogative, but he can no longer excuse his belief in the name of reason and moral necessity."


Lawrence Krauss
A belief in a god is just irrelevant to science. Science is how we understand reality.

Reality

Desire/instinct verse best rational behavior, like the eat/not eat of the epigenetic switched overeater, is a dilemma we face. It come down to choice. I no longer have the excuse of not understanding the real problem. To continue to eat as my instinct/desire demands is not rational behavior, yet the body wants what the body wants. I have studied this now, and understand, so I can no longer just eat until the desire leaves and claim to be rational.  Oh well.  Sugar and overeating sets the epigenetic switch, once in a lifetime.

We are driven forward at a cellular level. We do not have a choice but forward or die. The only meaning in life is what ever we paint on it; family, community, religion, business, education, knowledge, truth, what ever get you out of bed in the morning. We are just opportunistic organism living on a big rock. Meaning of/in life is a human construct. A concept, nothing more, and yet it gives satisfaction, contentment. Just because we can have a concept does not mean that it is real.
