The point is still the same....how did the universe come into existence?
BTW, the Big Bang has nothing to do with the Theory of Evolution.
I know that, but the point is valid for both theories. If creatures evolved, what did they evolve from? What was the very first thing under the evolution theory and how did it come into existence?
Accidents happen. Humanity and matter itself were big ones.
The origin of life has nothing to do with Evolution. You can fully teach Evolutionary theory in schools without mentioning the origin of life at all. Darwin himself in his entire life only addressed the subject of the origin of life in a couple of sentences in a private letter where he speculated on it; he didn't have a word on it in anything he officially published.
The overwhelming majority of FR Creationists spend their time attacking theories of abiogenesis (life from non-life) and actually no time attacking evolution at all, ironically, because they don't even know what evolution is.
And no matter how much I point the above out, it continues, so they're obviously too dense to recognize reality.
The "first thing" to be subject to evolution was the first living thing which was able to (i) reproduce itself (ii) without each copy being perfectly identical to the original.
The Theory of Evolution does not address where that "first thing" came from (just as, say, the theory of gravity doesn't address where matter came from). But Darwin wrote, in the last paragraph of On the Origin of Species, that it was "breathed by the Creator." Which, incidentally, is what I believe-- God is who created us, evolution is how.
