The space is big, but time is vast too. There was a time in the universe when the entire universe averaged a temperature conducive to life and there was oxygen, carbon, and other crucial elements available (although not as plentiful as now). Life could have formed then, and largely died out. In fact life may only pop up rarely in both space and time, so rarely that it’s unlikely two planets have life within a detectable distance at the same time. In fact it’s even possible a highly advanced civilization formed on the earth many millions of years ago, and at those time scales all detectable traces of its existence would be wiped out. The scales of time and space are so vast we fail to comprehend how infinitesimal our scales are and make huge assumptions about what’s plausible based on our scales projected to universal scales. That’s geocentric! Also, possible doesn’t mean plausible. Objects can teleport to the moon through quantum principles it’s just so unlikely it’s never actually happens in reality. Life may be such a vastly implausible thing that our existence is a miracle so improbable it beggars the imagination.
