The first. I think the most likely resolution to the fermi paradox, which is not that paradoxical, is just that abiogenesis is a galactically rare event. Other proposed filters, like the advent of sexual reproduction, eukaryotes, or intelligence, seem much less robust to a failure of imagination.

My opinion, for what it's worth, is that every step is a hard step, because it's not just a matter of time elapsed to the next one, but of each step having to be taken in just such a way as to set the right preconditions for all the subsequent ones.
