As you clearly aren't - and thank you for the insult - one can only assume your inability to answer the question is deliberate.
Edit, rather than avoiding the question as it doesn't fit in with what you want to hear, could you answer it?
Do you feel able to elminate something as a possibility if you believe wholeheartedly that it doesn't exist?
It would depend on wholeheartedly - if I could proof it didn't exist of course I could dismiss it.
However if I had one option which I didn't really understand but felt it was unlikely, but had no better theory. I could not dismiss it. Even the most unlikley things can be true, and if you have no knowledge of other theories - the fact that one seems unlikley doesn't mean the others can't be even more unlikely.
I can reasonably safely dismiss the gryphon, cos I understand what is puports to be, and I have never heard anyone even claim to have gotten a gryphon to work. And also because I do have good theory of how else you may have gotten to work. As there are millions of other examples each day of how else it could be done. ie - I got the bus, so its quite reasonable that you may have done too.
However having not really got to grips with the concept of nothing - and then there being everything, created by a god of by other methods.
I really don't have the knowledge to rule anything out, and I have no other proven examples given to me everyday of how it is done elsewhere. Then there are the great minds through history who support a belief of God, not many for the gryphon.
Thats the situation you report yourself to be in - but choose to dismiss the theory of God.
I am more open minded, or willing to admit I really don't know.
