Well, I'm really not qualified to answer, but I think it's because regardless of how small each individual piece of "debris" would be, together it should still form a huge amount of matter. All matter gives of electromagnetic radiation. If there was normal matter there, we'd see the electromagnetic radiation, but we don't. So it has to be something else. It's kinda like how we can see those epic cloud nebula formations. Those clouds are basically just dust and gas and other tiny stuff. And it's not as clumped together as you'd think, but we can still detect it lightyears away.

There are other more complicated reasons but this is a pretty good answer. Basically that matter at some point must have been at the Big Bang and with all the heat generated around that time some of it must have interacted with the debris that GP is talking about. We don’t see evidence of that. It’s important to remember that though we as humans lose things all the time. The universe cannot. We got what we got.
