Complex sentence: The topic is currently still evolving, and some geologists associate the glass not with impact melt ejecta, but with radiative melting from meteoric large aerial bursts, i.e., the glass would be analogous to trinitite created from sand exposed to the thermal radiation of a fireball.
Split into simpler sentences: The topic is currently still evolving, and some geologists associate the glass not with impact melt ejecta, but with radiative melting from meteoric large aerial bursts. If that were the case, the glass would be analogous to trinitite, which is created from sand exposed to the thermal radiation of a fireball.
