WRONG. Your probability only applies if the population : (all the planets in all the galaxies - 1) are lifeless. Since we do not know if there is life
on those planets the probability has to be looked at differently. What we have is a SAMPLE of 1 out of trillions and that sample of 1 has a specific
property : life. What is the probability that a sample of 1 out of trillions is unique. The odds are so staggering that the proibability of life is
No you are WRONG as you put it. If we knew there was life out there we could estimate a probability of it happening on a planet to planet basis. At
the moment all we can say is that it has happened once. As we dont know how or why it has happened then we can not begin to produce a probability of
it happening again. Unique events happen all the time in this universe and life might have been one of them. Just because you are dealing with large
numbers does not guarantee something will happen more than once.
Think of it this way just because there are over a sextillion number of planets out there : do you think there is someone else out there who looks
exactly like you? Has the same name? Has parents that look the same? Has lived exactly the same life and will continue to do every thing you ever say
or do in your life until the day you die? Interacts with every atom and molecule in exactly the same way you have ever done or will ever do?
Of course not , the idea is ridiculous. You perform trillions of unique events every day, now multiply that by everyone who is alive on the planet,
everyone who has ever lived and will ever live. Factor in every living thing.
So what this demonstrates is that countless unique events that are happening all around us all the time. Now what if whatever sparked off life was one
of those unique events? What if it could only ever be sparked by those exact conditions at that exact moment? What is life was made by a long , long
chain of unique events over a very very long time?
At the moment we don't know what sparked off life. We have been trying to search for an answer to how it happened for a while now. All we know for
sure is that its not easily done. Everything live we have ever seen alive comes from 1 cell way back in the past. Its all part of a single family
tree. We have not been able to find anything that does not fit into that tree.
So until we can work out how life was made , discover something that does not fit in the family tree or just discover life on another planet we CAN
NOT produce a probability of it happening again that is anything other than 1 in (all the planets in the universe). Its simple maths , dont let the
large numbers fool you.
I hope it is out there even though the odds are stacked against it.
