Did you ever get into a discussion of the possibility of reincarnation only to have someone announce, “Reincarnation is impossible because there are more people alive now than have ever lived”?
And then they sit back smugly. Or perhaps they quote George Carlin, the favorite sage of the Barstool Philosopher.

Picking the right starting point seems to be crucial, and there is a certain amount of hand-waving involved, but see for yourself.
