“It’s only good as a thought experiment”. Framed as an argument. Did you notice you’ve switched sides? The Theseus ship paradox has at least 2 perfectly good answers, Is it dumb?

Another responder already gave you what you’re asking for: billion year timescales. You countered “500x”. Did you multiply 500 times x (47) and compare that to a billion? You latched onto that idea eagerly because it supported “your side”, but I’m sure once you think about it you’ll see it’s only a tiny fraction of a real counter argument.

You mistake me for an opponent. Me insulting you would look different. You’re the only one that can benefit from these comments I’m making to you.
