The universe is probably infinite, so unless the chance of life were 0, there should be infinite amount of life elsewhere?
If you're skeptical, using the drake equation, you can get
r=7
fp=30%
ne=0.005
fl=1e-11
fi=1e-9
fc=0.5
L=50
N=2.6e-21
that equals to 3.8e20 civilizations per galaxy, but i'll round it down to 2e20 because the milky way is pretty large compared to others. there are 1.7e11 galaxies in the observable universe, so, probably no life we can detect.
On the other hand, optimistic values would give a very different result.
