Answer:
Darwin's theory of evolution is when species are taking time to evolve from the original organism so in order for this to happen there has to be an original species so he also said that we came from apes if the world was 200 years old that still wouldn't be enough time for us to evolve how he said so in order for his theories to be even remotely correct it took time for this to happen so the age of the earth in a way helps support his theory
