Hi Ros:
We've talked before. (So this is a return visit):
You Said:
"I will just point out that logic does not necessarily equal fact."
The word "necessarily" is not necessary. I would never make the claim that logic = fact. That is why I was very careful to mention that one's premise ought to be factual. Arguments are usually stated in a SINCE...THEREFORE format. The SINCE part is your premise. If your premise is wrong your conclusion is doomed.
Most of "logic" has to do with showing how a conclusion does not necessarily follow from some fact. But sometimes the problem is in the so-called "facts".
Atheists often repeat the statement "extraordinary claims require extraordinary evidence". When you really understand that statement you will understand the Atheist conclusion. Humans aren't very good at logic. The brain evolved under circumstances that require quick judgement based on very little evidence. Some call this intuition. Intuition is "natural thinking". Intuition works fine in most circumstances because the payoff is immediate and requires little time wasted in figuring things out. Belief in GOD is intuitive. "All things are made by someone - there is therefore someone who made ALL things." After making that affirmation the ordinary hunter/gatherer can go back to hunting and gathering. Religion doesn't stop there. It starts saying you owe some percentage of your time, energy, money, ritual to please the MAKER. At that point intuition is no longer cost effective because you are not going to get a return on your investment. When you see that RELIGION doesn't work you start probing the premise.
Logic is for those times when intuition doesn't work.
