Watch the link John posted, and the approach given as to teaching intelligent design, or, as others would have things as well as themselves called what they wish, creationism, this obvious little snippet, as we go thru all our learning, all our successes , by the greatest minds ever, this little snippet is omitted.
If you dont change the terms of what were talking about, creationism, then you have to start at the begining, which is itself creation, and this is not discussed here, and to me, is the very heart of the discussion.
If someone says, man created this, how do we know?
It could exist in differing forms, or from a previous civilization, in a star, even a differing reality, as we shouldnt hold ourselves to be limiting Gods abilities, as we think this too may be possible.
And if you do, with no possible way to prove man has created, on his own, something from nothing, something thats never existed, we truly dont know, and only faith in such things will get us to believing such things, and again, we are at step one, so it is inarguable
