There are 10 to the 18th number of seconds in 30 billion years. There are 10 to the 82 number of atoms in the universe. The mathematical number for impossible is 1 in 10 to the 50th power. The chance of evolution occuring if you disregard the many rules of science ( biogenesis, thermodynamics etc) is 1 in 10 to the 40,000th power. Fred Hoyle and N. Chandra Wickramasinghe are the scientists who worked out the number. I personally can't ever believe atheism exists based on the science and maths, while science can disprove evolution, science and God can still coexist. So yes we are here and science says its not through evolution so make of it what you will.
