I am equally agnostic about everything for which I have no empirical evidence.
I do believe there must have been a creation event, for I have empirical evidence of creation, I exist. I cannot fathom infinity.
I am not surprised that conditions are favorable to my existence, as I believe in my own existence.
I am not agnostic about biblical literalism because, for example, I have empirical evidence that noah's flood never existed.
In my agnostic view no hypothesis is held as stronger than the evidence it explains and the predictions and subsequent validations it makes.
To me that is what agnosticism is all about, it is admitting to humanities limitations and weaknesses. It is not about ignorance, nor knowledge, and especially not about cowardice, but about truth. As I have said before there is accumulated scientific knowledge and there is personal belief, but there is no truth that humans can understand. It is a human idea which, like infinity, can be approached but never touched. Truth is the sum of all time and space.
Those who are brave enough to say "I don't know" typically make the best scientists.
As Nietzsche put it:
Finally consider that even the seeker after knowledge forces his spirit to recognize things against the inclination of the spirit, and often enough also against the wishes of his heart - by way of saying No where he would like to say Yes, love, and adore - and thus acts as an artist and transfigurer of cruelty. Indeed, any insistence on profundity and thoroughness is a violation, a desire to hurt the basic will of the spirit which unceasingly strives for the apparent and superficial - in all desire to know there is a drop of cruelty.
Nietzsche, Beyond Good and Evil, Our Virtues (229, last paragraph)
Other quotes:
"I have approximate answers and possible beliefs and different degrees of certainty about different things, but I'm not absolutely sure of anything, and many things I don't know anything about, such as whether it means anything to ask why we're here, and what the question might mean. I might think about it a little bit, but if I can't figure it out, then I go on to something else. But I don't have to know an answer.... I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn't frighten me. ~Richard Phillips Feynman
Thomas Huxley was the father of Agnosticism and had this to say:
"...every man should be able to give a reason for the faith that is in him; it is the great principle of Descartes; it is the fundamental axiom of modern science. Positively the principle may be expressed: In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration. And negatively: In matters of the intellect do not pretend that conclusions are certain which are not demonstrated or demonstrable. That I take to be the agnostic faith, which if a man keep whole and undefiled, he shall not be ashamed to look the universe in the face, whatever the future may have in store for him."
