Sorry, you can't escape that way. My answer is, whatever definition of life you like. I don't care what it is. You get to choose. For the sake of the hypothetic

Sorry, you can't escape that way. My answer is, whatever definition of life you like. I don't care what it is. You get to choose. For the sake of the hypothetical, we have scanned over the entire universe for that sort of life, and then we use the same definition of "life" for our declaration that there is no evidence of "life", so you can't escape through equivocation between those two definitions either.
