2 ideas:

1. simple life might be common, complex life is super rare. evidence suggests life/organic compounds/single celled life arose relatively quickly as soon as conditions were favorable suggesting the procedure might be common or easily done. it took relatively much longer to evolve to multicellular/more complex life suggesting this is less common/harder for life to achieve. each filter from here on in seems to get harder and more fortuitous. just think, if brutal dinosaurs were never crushed, thoughtful relatively harmless mammals may have never had the chance to dominate due to being so low on the food chain.

2. there hasnt been enough time. not a single star has truly "died" yet. not a single black dwarf exists yet because there hasnt been enough time for them to form. every star thats ever nova'ed is still in its white dwarf/neutron star/black hole whatever phase. this to me seems like the universe is still "young" (i know young isnt the best word since every passing moment is the oldest the universe has ever been.) tl;dr we are the achient first intelligent lifeforms
