There is a simple explanation given by the Fourier transform: That operation turns a space variable into a time one and inversely. The last dominant life form here on Earth was the dinosaurs 65 millions years ago. Earth life has taken that time to produce another dominant form, assume that is typical. So by Fourier transform, we can say that the nearest dominant life form similar to us or dinos is some 65 millions light years away. That put us alone not only in the Galaxy, but all the way in the Virgo super amas. If one out of two or three dominant life form produces a technological civilization, then there could be one every 200 millions years or so in the Virgo super amas. Note yet that this assume every galaxies are similar to our own. This is false, most are gas stripped elliptics where high metalicity stars can't form. So there may be entire galaxies with nearly no planets. That may reduce the life probability by a factor of ten or more, giving one civilization in Virgo every two billions years. Given the Universe age, we could well being the first. The next could be at the precambrian state ( first multicellular organisms) or even single cells discovering the new possibility of nuclear organization. Y.
