well I am looking more specifically for the equation of this, which includes variables and the possibility
of life giving rise in exactly the same way... here we are afterall, we are one way. Are you saying your equation for this is just 0 ? it's almost
like saying we do not exist.
I'd say the chances of that are rather slim 
can you show me this in a formulated equation
Let's for a second pretend some islands are other planets "similar" to our own.
how can we even begin to imagine or pretend without data
or an equation ? I would like the equation to start off asking the question... "here we are" if you claim the chances are very slim with no supporting
equation then that is like saying we are very special in the universe and this chance of happenings was most miracle like, we are unique... but if it
is not a miracle then why are the chances very slim if we are made of the most common stuff in the universe ? if we're common then there should be
life like ours (all life on earth) everywhere in the universe. because we are here)
Just look at the incredible number of species that only exist on one island and nowhere else, even if the environment is similar in the
region.
I agree all that stuff is here and all of it is evidence of atleast only one way the universe gives rise to life (planet earth) I am
looking for the math here... all we have when we ask this question my topic wants to address, well all we have is earth and what we know to give us a
foundation and a start to the question.
Humanoid lifeforms maybe, but exactly like us to the point where we would call them homo sapiens, I highly doubt it...
why doubt ? lets
use symbolic math for this... if life is here and this is a successful way in which it gives rise then there must be atleast 1 other place just like
this... perfect distance from their star, have an external object producing tides and winds, having a magnetic field, ect... if we apply the math
approaching the question with "yes" here we are, here life is... the math I am sure would come back to reflect more than 1 exact same place
(regardless if there are other ways or not) all we have to go on is ourselves and what we know, we are 'fact and 'evidence' of life... why look into
the unknown or pretend ?
in fact why are scientist searching for planets at same distances from their source star at the moment ? it is one of the latest trends in
astronomy...
