I find it hard to believe that we are the only intelligent life forms in the universe. What I'm going to say now will cause a lot of disagreement with me - but I'm going to state MY opinion and I don't really care to argue about it:
The Bible does say that when God created us he said, "Let us create man in OUR own image".
So I believe that the form we are as humans is in the image of God.
it wouldn't shake my faith not one little bit to find out that our universe was just part of a larger galaxy of universes - maybe even each with their own God.
We being created in God's image could very simply mean we are designed in a way similar to God. For example, if I say I created a computer in my own image, does that mean the computer must look like me; or would it suffice to say that the computer has a short-term working memory like I do, a long term memory like I do, an electricity-based neural system, a cooling system and so forth? Broadly interpreted, "in his image" could simply mean that, like God, we consist of atomic matter.
I think the idea of God as looking like man is a sticking point with evangelicals, but I don't think modern science and the bible can be reconciled unless the bible is seen to be at least somewhat allegorical. Even as allegory, it is astounding how much the bible gets right. "Let there be light," for example, sounds an awful lot like the Big Bang. And although the bible gets the order of things a bit wrong, the idea of the universe being created in an orderly and predictable way over time is certainly consistent with our current understanding.
It could very well be that God reveals Himself within the context of man's capability to understand Him at any moment in history. Even with all of our sophisticated technology, we are today incapable of truly understanding infinity, omnipresence and omnipotence. We are programmed to seek all of these things. We want to live forever, be everywhere at once and have power over everything. Maybe we are created "in His image" in that sense.
These, and many more, are the questions the agnostic seeks answers to. Or at least this agnostic does. I have no doubt that when the rubber meets the road and I am confronted with my own fallibility, I will gravitate toward faith and embrace the Christian God. Within the context of Christianity, even within the context of my native Catholicism, there is plenty of room for differing interpretations. In the meantime, I think keeping my mind open to all possibilities gets me closer to the truth than blindly following one particular doctrine.
I know who I am, and if there is a God, I think I know what He expects of me, given how I have been programmed. In my case, he has made my life mostly an individual journey as opposed to a collective one. If and when I find him, I'll have to emulate Frank Sinatra and "Do it My Way..."
