Each everything in the universe is extremely complicated, not simplistic
enormous processing has been put in to create trees, animals, men.
flower is not as simple as a plastic flower, even plastic flower, itself has undergone lot of processing from the raw material to the finished product, not to speak of a real flower to come ut as fragrant beautiful, to be able to procreate .
nothing is simple 
open the body of man , you will see the complex structure and processes that have been inputted by nature,
may be you may have to relook at yourself to revise your theory of simplicity
