Hate to say it, but this line of reasoning is why you must be a liberal.<quoted text>
What's stumping scientists?
"During early embryonic development, organ systems develop on an "as needed" basis. The brain and spinal cord, for example, which are required to control and coordinate the functions of other major organ systems of the body, are the first to form. At the end of the third week, the embryo is about two millimeters long and the blood vessels and alimentary canal have begun to develop. By the end of the fourth week, all major organs have begun to develop and the heart beats for the first time."
For some reason, liberals seem to have a very difficult time zooming out to see a much bigger picture.
You're describing what scientists know - not what they don't know.
It's more about what they don't know. For instance, they don't know why cells begin to divide on their own after conception.
Neither could they recreate that in any lab from scratch.
