The reason you are having trouble debating is because I am holding you to the standard you claim to meet. If evidence and reason are the deciding factors, then present your evidence. Any position in the absence of evidence has no claim to reason.
Another reason you are having trouble is that you are still a Christian. I have told you multiple times that I am not a Christian and I have never been a Christian. Nor am I Jewish or Muslim. Yet you want me to explain how I can believe in God and not the Flood? I am giving you facts and you are ignoring them. Yet you want me to accept that yours is a rational position.
Simply because you or the scientific community lack a complete understanding of something does not imply a theistic explanation carries any value. Even if there exists some topic on which science can never speak, any understanding could potentially evade us forever – supernatural or metaphysical speculation would not automatically be correct. Uncertainty is the most legitimate position.
Lightning, earthquakes, volcanos, disease, mental illness, speciation, planetary orbits and numerous other phenomena have been historically labelled ‘supernatural’ only to later be more thoroughly and elegantly explained by science. In fact, every mystery ever demonstrably solved has had a non-supernatural explanation. To suggest that science cannot or will not explain a phenomena, and that only theism can, is hubris of the highest order.
Using ‘god’ to explain something explains nothing. God’s supposed powers and how they work are a mystery. An explanation is intended to clarify and extend knowledge. Attributing a phenomenon to the magical powers of a supernatural being does neither. Worse still, this presumption acts to prevent any deeper investigation, being little more than a form of blissful ignorance.
Theists also predicate godÂ’s existence on a lack of knowledge, not on any positive argument or evidence.
Every conceivable argument, every imaginable piece of evidence for god is not without some fatal flaw or more likely explanation which precludes it from being used as definitive proof.
