@Zacrates,
Xris,
I cannot speak for Alan, but after reading some of his writing, and understanding the human the way I do, as well as the preconceptions we are born into, and bombarded with on a daily basis, it is rational to recognize that we are all on a learning curve that will travel through various ideologies, IF we are actually travelling. If one is simply sitting on what he believes is the absolute truth and needs to seek no further, than of course that would not be a learning curve, that would be a hole.
It sounds as though Alan has traveled many of the same paths I myself have, through religious persuasions, tossing aside that bondage to seek something else but carrying some of that baggage with you until you are able to completely relieve yourself of it all.
I am not sure why you keep suggesting that we do not want to answer to questions regarding the existence of a Designer and why we think that one exists, because that is what we have been doing here.
What you are suggesting however is that if one exists that we should be able to describe it. And than you use our inability to describe the Creator of the universe as your reason not to accept that option. What I am saying is that is not an excuse to dismiss it.
Just because you cannot describe the builder of the Taj Mahal does not mean that one does not exist.
With regard to extraterrestrial life, I think it is the hgihest form of idiocy to think that we are the only life forms in the universe. the simple fact that the human can exist is more than credible evidence for the possibility of other life out there.
To dismiss that is akin to believing that trees exist, but there couldnt possibly be such a thing as a flower.
