If there is no God, then all things must have come about through evolution.
Evolution requires a series of small changes over a long period of time which develops an organism.
If evolution were true, I'd like to know how to explain this:
A caterpillar grows, shedding its skin along the way as it grows.
Question: How did the first caterpillar survive shedding its skin before the secondary skin evolved?
Upon the last shedding, said caterpillar's final shed reveals a headless, legless case. It is the chrysalis. Inside there are no organs, it's just a bag of thick, DNA goo. In two weeks this goo assembles itself into a butterfly.
Question: During the lengthy process of evolution, how did this creature survive the "goo phase" and procreate before the DNA learned to turn into something else?
Since caterpillars can only come from butterflies, but butterflies couldn't have been around to start with, how could all this be?
Ergo, I believe in God.
