IF we are not alone in this universe, I suspect the other creatures out there likewise possess intelligence, and will continue to evolve this intelligence to higher and higher levels.
Because we and they do not remain inanimate rocks or unthinking cells, we are in a sense developing into far less powerful versions of that God the scientists are so afraid of. If we are not made in His image, then whose? These changes are not random any more than the ordering of the universe is random. Whether it's a big bang, or the laws of gravity or relativity or quantum mechanics, there are rules underlying all of this. Science doesn't want to think about that big picture because it has divorced itself from all notions of philosophy and religion. But for all your explanations based on randomness, the scientists always hit a brick wall in trying to answer the "big" questions, because they find themselves talking in metaphysical terms.
I don't deny evolution for a second. But isn't it interesting that in a world teeming with life, and all the scientific study, we do not see any new life springing up any where on this vast globe? All these life forms are thriving in this environment, from elephants down to viruses, yet we don't see any inanimate chemicals coming together and forming an original life form. Indeed, scientists can't do it under controlled circumstances.
It's mutations. We track them. We count them. They're it. Deal with it.
RE: your last paragraph
1. the environmental circumstances that existed when life started do not really exist now on the earth.
2. we don't know for an absolutefact that life is not springing up in some form. Two reasons: first: we're not spending billions of dollars looking and, second, there's no reason to assume new living things would differ from the most primitive currently living things in ways we are prepared to identify.
