He did the same with all of life on the earth including animals and insects. Jesus created mature butterflies who mated and laid eggs. These then hatched out into little butterflies. That butterfly eggs would hatch into caterpillars is strange, amazing, astonishing, miraculous, surprising and wonderful. For if you plant a seed the plant that comes up is like the plant the seed came from.
Fish eggs hatch into little fish.
When you were conceived in your mother's womb you started out as an egg that developed into the human being you are, not into a caterpillar. The caterpillars live off the leaves of plants. As they grow they shed their skin several times growing up to 30,000 times in size. Finally they take a nap for a week or two and wake up as butterflies. During the nap time most of the organs and other tissues of the caterpillar break down, turning into a semiliquid.
