Again, we don't whether the universe 'came from nothing,' or if it's a part of a multiverse, or if its cyclic or something not yet imagined....so no assumptions should be made, not that 'it came from nothing,' not that it must have been created or anything else....the reality is: we don't know, we don't have enough information to know.
I don't know, you don't know, nobody knows. If someone somehow does know, they are either unable or unwilling to show that they do know.
