That response is logical fallacy both circular and bootstrapping.
And your response is nonsensical.
You know, FRiend, I've long suspected that "philosophers" like yourself must envy, even loathe, science because it produces a constant stream of near miracles, while most philosophers occupy a status one rung below starving-artists.
You produce nothing of value, but you are entitled to name-call and hand-wave at science for being "illogical", "circular" & "bootstrapping", etc.
The truth of the matter is that science is what it is, regardless of how "illogical" or "circular" you accuse it of being.
You of course are entitled to your opinions, just so long as you don't pretend they are "scientific".
