You’re presenting that argument to some who are absolutely cock-sure they are a member of a unique society on a planet that is only 6000 years old.
That is not as silly as it sounds, my sister who is "mostly" normal is adamant the Earth is only a few thousand years old, I say "mostly" as she has some seriously weird-arse oddball christian ideas that really take the cake.
Okay...she is sometimes plain and simply straight out religous screwy...then she throws a curveball and appears normal.
