Did you read this?  I suppose the portion you're referring to is from the end of the document.
Question 3:  I haven't read everything in detail but can you expend on the document on their religion?
EBOs [Exo-Biospheric-Organisms] believe that 
the soul is not an extension of the individual, but rather 
a fundamental characteristic of nature that expresses itself as a field, not unlike gravity.
 In the presence of life, this field acquires complexity, resulting in negative entropy [tendency towards order] if that makes sense. This gain in complexity is directly correlated with the concentration of living organisms in a given location. 
With time, and with the right conditions, life in turn becomes more complex until the appearance of sentient life. After reaching this threshold, the field begins to express itself through these sentient beings, forming what we call the soul. Through their life experiences, sentient beings will in turn influence the field in a sort of positive feedback loop. This in turn further accelerates the complexity of the field. 
Eventually, when the field reaches a "critical mass", there will be a sort of apotheosis. It's not clear what this means in practical terms, but this quest for apotheosis seems to be the EBOs main motivation.
The author of the document added his reflections and interpretations as an appendix. He specified that, for them, the soul field is not a belief but an obvious truth.  
He also argues that the soul loses its individuality after death, but that memory and experience persist as part of the field. This fact would influence the philosophy and culture of EBOs, resulting in 
a society that doesn't fear death but which places no importance or reverence on individuality. This 
"belief" compels them to seed life, shape it, nurture it, monitor it and influence it for the ultimate purpose of creating this apotheosis. Paradoxically, they have little or no respect for an individual's well-being.
Please be advised that I'm speaking from memory of something I read more than 10 years ago, so take the following with a grain of salt. Also, I'm not a philosopher or an artist, so please excuse my struggle to properly formulate the concepts and my dry terminology. Finally, 
note that this information comes from a document whose author was directly interacting with an EBO. It is not specified whether it was an ambassador, a crash survivor, a prisoner. The means of communication were not specified either.
Something similar surfaced recently. There's an analogous pattern in how it's written.
Biologics created by some intelligence as tools, with a mixture of terrestrial and artificial body mapping, who have a weak immune system, no survival related capability, night sight, are wrapped in a bio-film, excrete through their skin and live off 
hummingbird soup.
The anthropologists who 
interviewed the alien to document their 
hive precept should get a Noble Prize. The "guy" did not use poorly developed concepts or dry terminology. Life is a materialistic precursor. Consciousness is a boson of some undiscovered field. Memory and experience are the content of immortality. Transcendent purpose is the movement towards evolved divinity.
It's a trans-humanist confection, clearly a product of Scientific Millennialism.
