We obviously live in a matrix/simulated world, and it can't be older than 50 years, because before that, computers didn't exist. Checkmate christians.

Lead 204 is entirely primordial and the other isotopes found on earth would be found at roughly the same concentration were all of the lead on earth primordial. It's the excess ratios of the other isotopes of lead that can be attributed to radioactive decay. That is a substantial proportion of the lead on earth, but to say the "existence of lead" is proof of the age of the earth is entirely incorrect.
but who made the uranium?
But the half life of polonium 210 is just 138 days. other is a few days. radium 226 is 1602 years. Why couldn't the earth have started with a lot of radium 226? Checkmate round earthers.
Could have started with lead directly. Why go the extra mile.
There's evidence of human civilization and agriculture going back at least 10,000 years. You have to be extremely willfully ignorant to think the earth is only 4,000 years old. Hell the pyramid of Giza is older than that.
