A more detailed estimate for spontaneous generation has been made by Harold Morowitz, a Yale University physicist. Morowitz imagined a broth of living bacteria that was super-heated so that all the complex chemicals were broken down into their basic building blocks. After cooling the mixture, he concluded that the odds of a single bacterium re-assembling by chance is one in 10100,000,000,000. This number is so large that it would require several thousand books just to write it out.

And then when you have your one celled amoeba how do you randomly morph it into a woolly mammoth? How did so much genetic material randomly materialize?
They all had to admit that the odds of the virus living long enough or the bacteria living long enough to have food to eat or a mate to mate with was also impossible. Even an asexual example eating his own would never change into something else to have some other example to eat or mate with, so no evolution. All of these "scientific" claims of evolution cannot be shown possible with math. The claims made by non mathematicians about evolution are just their imaginations and cannot be shown possible by math.
