:this jibe is an example of science illiteracy. re "proof": no theory in science is "proven"; all theories in science *prove useful*, and a theory is used only until a more *useful* (more accurate or more widely applicable) theory comes along to replace it. (relativity did not "disprove" newtonian physics as newton used it.) re big bang: no other theory of the universe explains as many different observations with as much accuracy and internal consistency, and matches observations made after the theory was stated, as the theory of the singularity. in other words, it's tremendously useful.
