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.
