I think it extremely likely that at least primitive life exists elsewhere. Consider: current favored scientific theory is that all elements heavier than iron are the product of supernovae, and that these elements have been spread throughout the Universe as a result of supernovae. That is: everything in our Universe (planets, stars, etc.) have been thoroughly "salted" with material from other, long-dead solar systems.
Non-living matter from other solar systems is prevalent in **great quantities** - on Earth, on all of the other planets, within all of the stars of the galaxy and neighboring galaxies. Why wouldn't there also be primitive life forms (the most primitive, the type that can survive in space, plant seeds and lichen, moss, etc.) also distributed throughout the Universe as a consequence of those very same supernovae? Scientists call this hypothesis "panspermia".
If the hypothesis is true, what it means is this: a - life did not originate on Earth (so at least primitive forms of life did definitely exist elsewhere long ago) be - primitive life has probably been widely distributed, and so any celestial body able to support at least primitive life as we know it probably is host to at least primitive forms of life I think this is a very rational hypothesis.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
