The following is not a question: Can something come from nothing?

You have clearly not understood what a singularity is.
Don't worry, it's normal not to understand it... it is a difficult concept, as it is a warping of space-time, turning these into something beyond our intuitive understanding of both time and space.
I can only tell you that what you wrote makes no sense. It's sort of like saying "if the square has round sides,".

It's my understanding that the laws of nature came about just after the big bang, so I doubt that anyone can say they understand the nature of the universe prior to the big bang.

Which just renders your initial "guess" all the more wrong.
