Was logic invented or discovered?

[genkaus]

In the spirit of the pi thread here: was pi invented or discovered?, what are your thoughts on logic's existence?

This also comes about because someone, somewhere claimed that logic exists regardless of anything else, hence something can exist out of the Universe, which poofs a god into this kind of existence.

Logic is invented - in the sense that it requires a conscious mind to conceive of it and cannot exist without it.

It's also a system derived from the (many) observation (s) that our universe is such a universe.

That derivation from collective consideration of observations would not occur without the assumption of a knowable universe.
