No. It was a fact. You seem to have a problem separating fact from opinion. Were it an opinion, it would be easy to point to an example where science has proposed a non-naturalistic origin for the universe. That is not possible.
Lewontin's statement is a fact unless refuted and that is impossible because of the very definition of science.
"Again, we see the problem. You don't understand science."
I understand science just fine. You are simply willing to make any claim and say anything to avoid the truth of that fact. Unfortunately, you have zero evidence to back up your position while 100% of the evidence supports mine.
Deal with it.
Let me give you a quote from your esteemed Mr. Lowentin:
Birds arose from nonbirds and humans from nonhumans. No person who pretends to any understanding of the natural world can deny these facts any more than she or he can deny that the earth is round, rotates on its axis, and revolves around the sun.
