I won’t bother drawing that line-—>You Will. If the Big Bang, the so-called engine of matter has nothing to do with ‘speciation,’ then what does? If matter didn’t come into existence when the Big Bang (pagan Cosmic Egg) exploded, then Nature’s (capital N for nature worship) primary creative energy, evolution, had nothing to work on. So once again, if the Big Bang has nothing to do with speciation, then what does? The magical, mythological energy called evolution?!?
But no biologist needs the latter to infer the former.
