With our limited reach into the vast distances of space using land-based telescopes, and space-based Hubble and now Webb, plus our launched explorers including Voyagers l and ll (Voyager l reached interstellar space in 2012 and Voyager ll in 2018 after some 40-plus years of travel), we have barely penetrated near space in half a human lifetime, 40-some years, and still have no idea how many galaxies are out there in the many light years of space and time.
I mean Earth exists in a spot on a not particularly distinctive arm of a not particularly distinctive spiral galaxy, of which there are perhaps multi-millions. And IMO it's a remarkable humankind of hubris of some to think that of the trillions of possibilities of development in the endlessness of space, to us at least considering our short lifespans and non-existent ability to travel and discover over light years of time/space, to think that our planet is the only one with technological development is... well, I'll just say let's reserve judgment on that.
