Yeah, this is broken because all lead did not have to come from polonium, that's how half-lives work.

It's still 100% bullshit in every way, someone just needs to have chatgpt4 sort out the current mass fraction to explain why, I'm way too lazy to argue against insanity.

Lead-204 is the only isotope that doesn't derive from radioactive decay, and it represents only 1.4% of the lead on earth.

Was going to say exactly that, not all lead came from radioactive decay. So this kind of ruins their debunk, Earth's age has been measured by the amount of lead.
