Infinite number of planets with life

[rafa360]

there is no end for the universe, right?

Actually, we know not only how big across the universe is, but also how much mass is in it.

our planet is pretty "lucky" in his position with the sun, some centimeters away : to cold, some cm near: to hot...

This is also untrue. The habitable zone is estimated to be some 2.28 AU wide. Furthermore, the Earth's orbit is elliptical, so its distance from the sun varies between 152 million kilometers at its aphelion and 147 million kilometers at its perihelion. That's certainly not a difference of centimeters.

quote n1, I'm going to search about that when I can, but how do we know that? what comes after the universe? it has some kind of walls? what the name of the theory? or it is definitely like that? because I see all the theories, including the existence of a god as all possible ( I see the faith ones less rational....) just no one can prove it...

quote2 interesting and good to know but that's not the point, if the position of our orbit on the sun is not the the factor for life in earth, well a factor there is, magic, superpower or simply lucky are the lasts on my list...(but still in the list...) and the fact that the earth is here tell us that there is a probability....

thanks for the reply
