IMO, ancient UIEs likely practice direct panspermia of DNA life on all the nearby rare worlds on suitable liquid water zone planets capable of lasting billions of years without nearby supernova. But as noted, due to the near infinite paths of possible embryology cell division, it would be virtually impossible for identical development to occur beyond the simplest lifeforms.
That noted, it is true that some of the general forms of life successful on Earth due to the nature of gravity, mineralogy, atmospheres, geology if similar, are likely to result in similar niche general forms of life. So other worlds like Earth may have fish like life that eventually also left oceans as amphibians and then evolved into a great range of creatures like here. There would be herb-like life and tree-like life that might evolve monkey-like life eventually evolving appendages with hands etc. So yes, even monkeys like us. But all the internal structures would vary immensely due to random paths. On some worlds, a flying bird-like lifeform might end up as the first tool using intelligent creatures and that may be what God's Angels are.
Evidence of possible direct panspermia is the unlikely if purely natural, Cambrian Explosion of greatly varied lifeforms that oddly was never repeated. Like aliens plunked down a bunch of weird types from other worlds, only a few of many then dominated. Octopus were one of those.
