based on what we know
energy certainly doesnt just appear.
as for matter - based on what we know it cannot just appear from nowhere. It has to have a source and besides there is no set definition of matter
Yes, based upon what we know, matter and energy just exist and do not have an overall source.
There has been no evidence to suggest that either 'came from somewhere', as you seem to be suggesting, other than somewhere else in the universe.
They aren't magicked into existence by an invisible, intangible deity, as far as we can see.
