Hustler, pimp, whatever...
Hence "unlikely".
I don't lose sleep over it. There are so many ways to work around it, it's not even funny.
For example "I didn't create it out of nothing! I transformed it out of the nitrogen in the air!" Or "I summoned it from an alternate timeline!"
Plus, I think it's a mistake to tie magic TOO closely to science. As I've said elsewhere, there's an otherwise excellent Doctor Strange mini called
The Oath that did one thing I couldn't stand... it said "Magic cannot duplicate what science had invented", which falls apart COMPLETELY on casual examination.
Anyway, I think people read far too much into the "MCU is built on science" thing. All because of one bloody line in
Thor which was contradicted by events in the actual movie. Sure, humans BELIEVED science was paramount, but that's simply because they didn't KNOW about magic.
