It is possible abiogenesis is such a low probability event that it occurred once since the exact conditions weren't met. The earth is not very similar to early earth currently. Consider endosymbiotic hypothesis. The evidence is that it seems to have occurred at least multiple times (mitochondria, chloroplast, nucleus) in different geological eras. I would expect if life had a high enough probability to happen multiple times, it could occur in different geological eras.
