I had a conversation with a woman who strongly believed God put the dinosaur bones there to test our faith.

Some lead might have been created from supernova fusion, probably. I'm not actually sure if it's the right isotope or if lead even has radioactive isotopes that we know of

Don't give up, you can still change their mind.

Just from 4000 to 200.

We can't prove that the world we live in wasn't created last Thursday, with our memories, the growth rings in trees, and so on created by a (near) omnipotent trickster to deceive us. But science and rationality give us tools for determining what's worth taking seriously, and sorting out the reasonable, but unconfirmed, claims from the unverifiable hogwash.

We can't know anything with 100% certainty. We can always imagine some razzle-dazzle, imagined scenario to counter the rational explanation if we like.

The point of the scientific method and logical reasoning is to pick the explanation with the most evidence.

The existence of a god is something that can't be disproven. You can always find gaps in knowledge and explain the gap by saying a god / multiple gods did that. As gaps narrow with more knowledge, you can always just say that the holy books were just a metaphor in this one case, but the rest of it is literally true.

It gets even more complicated when you run into people who refuse to believe in any science, or anything outside their own personal experience.

Personally, I believe the Earth is a sphere. I've been to Australia, Europe, Africa, Asia and North America. The time the flights took and the routes the in-flight maps showed make sense for a spherical earth. So did the scenes visible out the windows, and the day/night cycle. The mere existence of time zones and seasons strongly suggests the Earth is a rotating sphere tilted slightly off vertical. But, it could be that I'm living in a Truman Show world, where everything is a lie designed to make me believe something that isn't true. I haven't personally done all the math, all the experiments, etc. to prove the Earth is a sphere. And, if this were a Truman Show world, the producers of the show could mess with my experiments anyhow.

For someone who doesn't want to believe, there's really nothing you can do to make them believe. The world really relies on trust and believing Occam's Razor.

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

Which raises the question of why he would create a planet with the illusion of age and send you to hell for falling for his own trick.

Of course, the universe was actually created in 1970 and anyone claiming to be older than 54 is an agent of Microsoft sent to test your faith in Unix.

Earth will be created in 2036. This is just a rehearsal.
