Prove to me that Argon isn't seeping into the rocks and fossils and contaminating everything that has been dated.

Gas doesn't seep into the middle of a rock. That's why we say "hard as a rock".

OTOH, if argon could seep in, it would also seep out which would be more probable and result in the actual ages of the rocks being many millions of years older than as tested.

But I'm supposed to be believe groundwater with carbon 14 does? Yet Argon can't?
