How about I prove you right:God was an astronaut. Prove me wrong.

One unspoken belief of God botherers is that we are important enough to warrant god's attention. With millions and possible billions of inhabitable planets why do you think that you are important enough to be even considered within god's field of vision?I mostly agree with you here, with these exceptions:
Also, a question for you: If the Bible cannot even contain a "rudimentary understanding of the will of the infinite," then how do you know it? Do you have dreams and visions? And how is your mechanism not subject to your own criticism of a "colossal ego trip"?
- the transcendent God has determined to condescend to us, for our benefit, to comprehend a measure of His nature -- as it is portrayed before our eyes in the universe, and as it is more specifically revealed in His word;
- the Christian faith, I'm sure you know, does not submit that the Bible is the "writings of men," as you would have it, but appointed prophets and apostles were guided by the Holy Spirit to reveal God's will; in their human capacity, the prophets sought to comprehend the very things they wrote, and the angels were perplexed; the unity of scripture is a testimony to its One Author. A group of fishermen, a Zionist, a doctor, and a Pharisee could not concoct a story that perfectly fulfilled a couple thousand years of the writings of dozens of prophets, especially as it defied everything that they were by nature, and exposed even themselves to be wretches and fools; Paul was respected by both the Greeks and the Jews; he tossed this all -- he became a fool -- for Christ.
Or do you rather conclude that you and I have absolutely no way of comprehending God -- that He has made no exposure of Himself in any way?
I live on Planet Earth. My comprehension of life ends at the the edge of this solar system, with 99% of the emphasis on life here on Earth. I started out 50 years ago to seek the truth. I set out on that journey with a blank slate and an open mind. That journey too me into an array of different, books, people and experiences that are the foundation of my understanding. I'm not saying that I know enough to tell people anything. What I tell people is to make their own journey because the truth cannot be handed to you. Most people choose not to be bothered and settle on hand me down "truths" of those who went before. What we end up with is a bunch of ignorant people who really have no clue what is going on, but they can sleep soundly at night because there is nothing of any substance in their heads to cause them any thought.
If you believe that there is a god that takes any interest in our species, above and beyond all others, then would it not make more sense that it would give its word to all people, in all historical time frames in all geographical locations? If the bible is the only word of god, then this god is incredibly inefficient in getting its word out there. Would this not give one doubt as to its omnipotence? Believing in the bible as the only word of god, to me, is to deny your god's intelligence and thus your own.
