Yeah, even later origins (which usually are suggested to be around 3900 million years ago) are still pretty early which could totally suggest that life is almost an inevitability if the starting conditions are right. This is one of the reasons I'm pretty confident our very own solar system has plenty of unicellular life outside of Earth. And if panspermia has been indeed going on, then those lifeforms may end up being rather boring due to their similarities to terrestrial life! If multicellularity has also evolved, those creatures could be much more interesting.
