Drake’s equation

1.      There are one trillion stars hanging in the sky

2.      And another trillion planets orbiting these stars

3.      All of them may have supported life at some time

4.      While a species may appear evolve and die out

5.      There are 1 trillion different species on our planet

6.      We have been able to identify 10 million of them

7.      –We may consider only us intelligent however–

8.      But assuming a trillion different species out there

9.      How many of these will be intelligent after all?

10.  On planet Earth how many people are the same?

11.  Out of 10 billion people our friends are just 100

12.  1 in 10,000 worlds may have life at the moment

13.  1 in 10,000 of these lifeforms may be intelligent

14.  1 in 10,000 of them may have communications

15.  Out of a trillion stars the Sun will be alone.
