There are 8 components necessary to make life possible
and develop, with all its possibilities. This can also
cause 8 failures. Thus, the chance of life arises 1 to 9.
That corresponds to a share of 11.11%.
The probability factor is therefore F_{L}
= 0.111 = 1:9.
Further developed, from equation 3.1.1 results for the
number N_{Le}
animated "earth 2" in sunlike systems
:
4.2.1 Equation 
N_{Le}
= N_{he }·
F_{L}
N_{Le}
= A · F_{sph }·
F_{gae }·
F_{L}
N_{Le}
= A · F_{s }·
F_{p }·
F_{h }·
F_{g }·
F_{a }·
F_{e }·
F_{L} 

Since two values exist for F_{e} or F_{gae}
a minimummaximum statement can also be generated here:
Inserting all values (F_{e} = 0.1) into equation
4.2.1:
N_{Le1} = (100300)·10^{9} · 1:15,000
· 1:69 · 1:9
N_{Le1}
= 10,735 – 32,206 habitable „Earth 2" with
life
Inserting all values (F_{e} = 0.01) into equation
4.2.1:
N_{Le2} = (100300)·10^{9} · 1:15,000
· 1:691 · 1:9
N_{Le2}
= 1,072 – 3,216 habitable „Earth 2" with
life
The two results can then be summarized to the following
statement:
4.2.2 Theorem 
The number of solarlike
star systems, with a habitable "Earth
2" in the galaxy, which could carry life, is
probably 1,072 to 32,206. 
The probability for an "Earth 2" with life, in
a sunlike star system, in our galaxy, is then:
4.2.3 Definition

F_{Le}

· F_{gae}
· F_{L} 
F_{Le} = F_{sph}·F_{gae}·F_{L}
F_{Le}= 1:15,000 · (1:69  1:691) · 1:9
F_{Le}= 1:9,315,000 – 93,285,000
Only every 9.315  93.285 millionth star
system then has an earthlike, animated planet.
