Did God create evil?

I’m not very well known with the contents of the bible.
But I think that God created everything, including good and evil.
Or maybe the Devil created evil?
But God, probably, created the Devil.

My question: was it so necessary to create evil at all?
Could they not have thought of another concept?
Like, only good?
I mean, who likes evil?
Do we even need it?

So yeah, that.
