So your argument is that you prefer to ignore parsimony because you don't think your fish care one way or another? Being a sentient person with concerns more advanced than a goldfish I don't agree with your assessment, although you are welcome to model your philosophy after a fish with a brain weighing 0.097 grams.
Heh, since ID seems to have it's varying degrees..from zealot creationist to agnostics. So too does the word consciousness mean different things to different people. Does our sentient existence in anyway trump that of a fishes? And if a fish is more intelligent than a worm, can humans with our superior intellect surmise something may exist more intelligent than he/she is?
Is it possible for superior intelligent beings to exist outside of our ability to observe them like in some other dimension we can not comprehend. And if such intelligence does look on us like fish, is it any wonder our primitive arrogance and self importance keeps them amused. :D
If that is the case it would be all the more amusing if, from our perspective, the fish chose to be "humble" and think like the scum on the walls of their bowl. There is no excuse to act stupider than we are because other things "get by" with less than what we are capable of. There is a difference between arrogance and healthy self-esteem.
All I know is that energy through the processes of the universe manifests conciousness in many forms to include humans. The how is a matter of science and the why is a matter of religion.
