The famous astronomer and mathematician Sir Frederick Hoyle calculated the probability of the spontaneous generation of life:
No matter how large the environment one considers, life cannot have had a random beginning. Troops of monkeys thundering away at random on type writers could not have produced the works of Shakespeare, for the practical reason that the whole observable universe is not large enough to contain the necessary monkey hordes, the necessary typewriters, and certainly not the waste paper baskets required for the disposition of wrong attempts. The same is true for living material.
The likelihood of the spontaneous formation of life from inanimate matter is one to a number with 40,000 noughts after it……it is big enough to bury Darwin and the whole theory of evolution. There was no primeval soup, neither on this planet or on any other, and if the beginnings of life were not random, they must therefore have been the product of purposeful intelligence.
