Whatever the physics of the parent universe are, they either prohibit BBs (and then that universe would be ours, which it presumably isn’t) or are unlikely to affect BBs in a way that disallows creating BBs that observe a similar universe. It’s akin to “why tf I’m a human on Earth 2024 of all planets and things” argument. Well, four reasons: you’re, a human, here, now.

Even if we assume that this universe we observe as BBs is as well the parent universe, it can produce not only human BBs obviously and not only coherent experiences. Complete nonsense is normal here too.

So if a universe allows for BBs (iow, spontaneous temporary observers with state that somehow produces the me-is-observing effect), it allows for all sorts of experiences, and given enough iterations could reconstruct itself and everything imaginable and unimaginable in a sequence of arbitrary length. “You’re certainly not”doesn’t follow here. It may be or it may be not. You’re a human, here, now.
