Do you think numbers were invented or discovered?

Numbers show up in a lot of different cultures. If we all independently reinvented / rediscovered the same thing, that’s interesting - don’t you think?

Does convergent evolution prove that a structure like an eyeball exists in some abstract realm, or does it mean there's a process which - given a similar environment - will produce that structure over time?

It's not hard to see why the same useful inventions emerged in similar environments.
