Why is Tyre Still Here When God Said it Would Sink Under the Waves?

[Jackalope]

That's what I keep telling you. It doesn't exist. The Bible says it doesn't exist and that's good enough for me.

Any claims of Tyre's existence, like the claims of evil-ution, must be lies straight from the pit of Hell.

Lies from the pit of Hell? Its a geographical fact that the city exists:

And if you look up Tyre in the map in your Bible and compare it to the location of said city on a map, it's the same location

Should I tell him he's being had?

No. Definitely not.
