Nor and or

[smelvanzq]

Hello! Good day! I have a question in this sentence
Matter cannot be created nor destroyed
Why nor is used here? Does or cannot be used here?
Pls give me some examples using or and nor in sentences without either and niether.
thank you so much teacher!

I would use it this way:
Matter can neither be created nor destroyed.
Matter cannot be created or destroyed.
You example sounds strange to me too.
