Of the hard cast variety
Given our current understanding of the universe, reality seems to agree with you.
However, I'm open to both ideas until one is ruled out unequivocally. We didn't know energy could transform into matter until Einstein, who's to say that we're not missing something in E=mc^2 that doesn't account for 100% of the variables. Our resolution may just not be good enough to notice we're missing it yet. But that's just my speculation.
Again I agree.
Things certainly could be found that would change our current understanding but for right now I am going with what we got.
