Define science, and then tell me how such a methodology “proves” evolution and the age of the earth.
Good grief - are you that dense? Science is a method of organizing and measuring observed phenomena, hypothesizing about their origin and meaning, and making predictions about the relationships within and between them and other objects in the natural world. Science “proves” nothing, it never has, it never will; proof isn’t the goal of science. The goal of science is to take all the information regarding a phenomena that is available and create a model that describes it and the processes associated with it.
