And you’re making the assumption that it could be. Why am I the only one who needs to show anything?
"Could be" is the null hypothesis.

Hmm I'm guessing you don't have children.
What do you mean, “certain of the answer?” It’s math
Oh dear. I dunno where to start here... but basically while maths itself is either true or false, our certainty of a mathematical truth is definitely not. Even for the cleverest mathematicians there are now proofs that are too complicated for humans to understand. They have to be checked by machines... then how much do you trust that the machine checker is bug free? Formal verification tools often have bugs.
Just because something "is math" doesn't mean we're certain of it.
Can I ask where’s your proof?
I don't have proof. That's my point. Your position is no stronger than the opposite position. You just asserted it as fact.
I wouldn't recommend it. Installing Python packages not in a venv is asking for trouble. Why do you care anyway?
