I know arguing on the internet is pointless, but here it goes since you seem to be making quite a few absolute statements about things which cannot be answered in any definite way, and that neither you nor I have even the slightest hope of ever understanding properly. Since you disproved the watch analogy by picking it apart into little bits and falsifying them, I'll do the same.
Firstly, you state that there are millions of stars, and a lot of chances for life out there. I agree, I did not state otherwise.
Secondly you ask how an omnipotent consciousness came about. I do have trouble answering that, in fact I have absolutely no idea how an omnipotent consciousness could come about. How did something occur from nothing? I also have no idea, I just know that it did, as I exist, and so do you. The question of whether all these millions and millions of stars and life forms came about by random chance, or by something closer to a mind than it is to anything else, is not a scientific one.
Thirdly, the universe is significantly larger than 70 million million million million times our size.
Fourth, I do not know where you got the 90% statistic from, but theism does not go hand in hand with arrogance. There may be arrogant theists, there may be humble theists, but keeping an open mind to the possibility that we are something more than a mechanical dance of atoms is not something I would consider arrogant. I would consider you claiming to know with certainty that theism is wrong, that god does not exist, and that the hundreds of millions of theists around the world are faulty in their beliefs to fall under the category of arrogance however.
Lastly, I do not understand why our relatively small size in the universe compares directly to our relative worth. Personally I would consider a single human life to be infinitely more important than an entire lifeless galaxy of stars and planets. Perhaps that is arrogance, however I will never place the value of an object, no matter how large, over the value of life.
