You could say the exact same thing about the origin of intelligence. That your ignorance leaves open the possibility that your current understanding is flawed in some way, perhaps a fundamental way. Which means that while it may seem likely that intelligence was a late outgrowth in the evolution of time and space, that might not be the case. That intelligence, rather than emerging as a late outgrowth in the evolution of time and space, has existed always as the matrix, the source and condition of physical reality - that the stuff of which physical reality is composed is mind-stuff. It is Mind that has composed a physical universe that breeds life, and so eventually evolves creatures that know and create.
My point here is that if you profess ignorance about things you have good reason to believe in - such as the universe having a beginning and the Laws of Nature - why aren't you professing ignorance about things you have less certainty about?
Do I have good reason to believe the universe had a beginning? Someone posted an article about a model created which would indicate the universe had no beginning, using some sort of "quantum correction terms." Should I believe that, or not? I honestly have no idea. I simply do not know the science behind it nearly well enough to make any sort of determination.
As to the origin of intelligence, where have I claimed not to be ignorant about that? I don't know whether intelligence arose randomly or based on the actions of an intelligence. What I have said, and continue to say, is that the mere existence of intelligence (or of life, or of the universe itself) is poor evidence for the existence of a god or gods. If I do not know how something came into being, how can I say whether it required intelligence to happen?
