This might be true, we may be made up the atoms from stars, but then how do you explain the appropriate conditions for these atoms to survive?? Can stars just grow anywhere? My argument is that every piece of living organism needs the right kind of environment to live in and I'm assuming because stars arn't just floating around on the inside of Earth, that Earth does not have the right conditions for a surviving organism AKA human beings.. So, that being said, it's not possible that we're made up of the same atoms that make up stars and panspermia doesn't exist! Jrach339 02:15, 1 February 2012 (UTC) [1].[reply]

Although I don’t feel like the author has proven the theory of panspermia I do however feel as though she has provided me with a scenario of how it could at least be possible. Therefore if it is possible, no matter how unlikely, it may perhaps have happened. What I feel to be her key arguments relate to how microorganisms that have been frozen for 10-20 million years can still be cultured in a lab. This speaks to me about the possibility of an organism surviving both the extreme cold and time required to travel through space. As well, she states a survival rate of 10-21 is all that would be required to cycle life within the galaxy. These factors, combined with the fact that the earth is receiving tonnes of cosmic material on a daily basis, are what have led me to at least open my mind to considering the theory of panspermia as one which may actually hold the truth to the origins of life on earth.Cgree973 18:30, 5 February 2012 (UTC) File:A.CAWX.png[reply]
