Carbon-based does not necessarily mean "bilaterally symmetrical critters with cephalization" as most sci-fi writers like to imagine. In the
"Origins" PBS series, one of the great points that Dr. Tyson and his guest experts make is that we have been supposing that alien life will look like us, which is illogical. The basic body plan on Earth for dominant animals (tube-within-a-tube, symmetry, eyes on head, etc.), plants, etc., all depended upon the most fit for OUR PLANET. Hell, the our nearest intelligent extraterrestrial neighbiors could have gaseous "bodies," gelatinous bodies, be able to survive in a vacuum, communicate in ways we can't imagine, etc. The adaptations that are most fit to an alien world may result in creatures we may not even recognize as "life."
We are limited to what we have found in our backyard and have used that to compose the "rules." Yes, physics and chemistry have basic laws which we believe to be universal, but that has nothing to do with how alien species may store and pass genetic information, compose their bodies, etc.
THE BIBLE - Because all the works of all the science cannot equal the wisdom of cattle-sacrificing primitives who thought every animal species in the world lived within walking distance of Noah's house.
