I don't see why the big bang theory is mutually exclusive to christianity, after all, who lit the fuse?? And I think you need to do a LOT more research into what big bang theory is, because it's certainly not an exploding neutron, and it's a bit of a stretch to link it to evolutionary theory, as nobody, even with all the help of technology, has yet managed to create a self replicating chemical in the lab that could produce or develop into "life"
