Hi.

Thanks for the ping.

As you know I’m not a nuclear physicist.

Can someone tell me how the Uranium on earth got the extra neutrons?

Thank you.

Uranium is said to have originated in extinct stars, and has a really long half-life, so at least some of the lead comes from the decay of uranium; the uranium-lead ratio is used to date the age of the Earth.
