## 4.4 - „Earth 2“ with Life

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 FL = 0.111 = 1:9.
Further developed, from equation 3.1.1 results for the number NLe animated "earth 2" in sun-like systems
:
 4.4.1 Equation NLe = Nhe · FL NLe = A · Fsph · Fgae · FL NLe = A · Fs · Fp · Fh · Fg · Fa · Fe · FL

Since two values exist for Fe or Fgae a minimum-maximum statement can also be generated here:

Inserting all values (Fe = 0.1) into equation 4.2.1:

NLe1 = (100-300)·109 · 1:15,000 · 1:69 · 1:9
NLe1 = 10,735 – 32,206 habitable „Earth 2" with life

Inserting all values (Fe = 0.01) into equation 4.2.1:

NLe2 = (100-300)·109 · 1:15,000 · 1:691 · 1:9
NLe2 = 1,072 – 3,216 habitable „Earth 2" with life

The two results can then be summarized to the following statement:

 4.4.2 Theorem The number of solar-like 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 sun-like star system, in our galaxy, is then:

 4.4.3 Definition FLe = Fs · Fp · Fh · Fg · Fa · Fe · FL FLe = Fsph · Fgae · FL

FLe = Fsph·Fgae·FL
FLe= 1:15,000 · (1:69 - 1:691) · 1:9
FLe= 1:9,315,000 – 93,285,000

Only every 9.315 - 93.285 millionth star system then has an earth-like, animated planet.
