It is like saying that people in the past were more extraordinary than today, because all the people you read about in history did extraordinary things. Yep, because dull people rarely make history.
There is nothing “random” about a successful body plan. What works is a rather limited subset. Natural selection is in no ways “random”.
My point is the submarine is designed to work. That is, it's not the end-product of a virtually endless chain of prior random events that somehow ended up by (serendipitously!) getting it "just right" to do what submarines do.
Surely you can discriminate the difference between "design" and a "crap shoot" that somehow gets things right by accident.
