euclidean geometry is famously complete

Nah.

this doesn’t mean that “it’s impossible to create any consistent set of math statements that completely describes everything,”

It says far less than that: “It’s impossible for a mathematical system containing the natural numbers to be both complete and consistent.”

Reality has almost nothing to do with it.

reality itself could be a complete system, understandable from both the outside and inside if only viewed at the right angle…

This has been largely debunked.

hilbert’s dream is not dead yet,

I dunno what his dream was, but Hilbert’s program is very much dead.
