The assumption is that the only way lead can exist is via a series of radioactive decay. It is a way. It is generally created in stars by a much more direct process, not through radioactive decay.
Is there an emperic difference (like the isotope number or whatever) between lead created through radioactive decay and lead created directly in a star?
So the meme is incomplete, but the general point still stands from what I can tell, right? Stars take orders of magnitude longer than 4k years to create lead as well, and there is no way of lead being created that could happen in 4k years, unless you start getting into “God made the universe look old” territory?
I mean, it’s created at a cosmic rate in the right sized star.
You’d need to back up and start talking about the big bang and star formation, and at that point lead isn’t really part of the argument. Most elements exist as a result of stars smashing atoms as per my understanding.

In a single star the heaviest element you can make is Iron.
To get anything heavier than Iron, which Lead is, you need your first start to blow up making iron, and the stuff left behind to eventually form a bigger star, then that star needs to blow up (where you’ll get some gold, lead and a few other slightly heavier elements. Then the remaining parts of the star need to form a neutron star. You then need that neutron star to find and eventually crash into another neutron star, and thats where you get the really heavy elements like uranium.

Thats correct, but the meme is written as a scientific explanation and its is wrong/incomplete. To correct it, go with what you said, not with what the meme says.
Not really, the original point was to prove the earth isn’t 4000 years old. Even if this were the only way lead could be created I’m assuming some portion of the decay could take place in space and then be part of the earth’s formation.

So does that imply that Lead has existed in the universe strictly longer than Uranium? Is the meme entirely backwards?
I think it could, yes. Not much (more comes out in the neutron star on neutron star action), but yes some from single large start explosions.

Yeah, not really defending the meme. I just lazily cross-posted it from !science_memes@mander.xyz, but the discussion here has been great
