determination of cause by observed effect is not observation of cause.
But it gets us pretty close, doesn't it? Considering our limitations...
I see a lot of gobbledegook by creationists but I just don't see the logic behind their theories. We need the Creator to settle this matter once and for all, right now! But where is It? In Star Trek: The Motion Picture Vger was the most powerful and intelligent entity in the galaxy but all it was was a creation to assemble, collect, and transmit its data. Otherwise it was useless until it "joined" with its creator -- humans. Materialist scientists, like Vger, are constantly collecting and assemling data but we don't search for a creator, that isn't in their "programming." Even Christ recognized that some had no 'spiritual inclinations' and he called those that had them 'happy.' But in 2005 they don't seem happy; they seem to have a need for proof and explanation, because science and logic has wiped out the notion of a needed Creator. At least that's what Hawking said.
