And enough of this cop out "I don't know". And don't say "we" because you can't speak for anyone but yourself. Saying you have no opinion when you do is simply being dishonest.
Actually, putting words in peoples mouths is dishonest.
He never says he has no opinion, now does he?
There is no "starting premise" at all, chronologically. The only starting premise of science is that we can create meaningful theories from what is observed in the physical world, and this has proven to be a very powerful and useful premise to mankind.
We do not assume nothing + nobody = everything. We say...and it gets tiresome to repeat the obvious to you, but it never sinks in...we do not know. Our scientific knowledge of the world does not start from the "beginning", it starts from the most immediate and accessible observations and moves outward from there...including backward, more distant, smaller, larger, as far as the range of our observations and experiments and instruments and rational thought can take us.
Enough of this trite strawman n+n=e you keep popping out at irregular intervals. If anything, it merely shows how little you understand anything about science. But at least that would explain why you keep mistaking pseudoscience for the real thing.
