If humans remain conscious after death, do animals also remain conscious after death?
I'm trying to figure out if there is any fundamental difference between the spirit of a human being (the "breath of life" that makes humans alive) and the spirit of a disembodied (evil/unclean) spirit. The logic is that, if these two types of spirits are not fundamentally different, then it follows that if evil spirits are conscious, then the disembodied spirit of a human (when the spirit departs from the body upon death) also remains conscious. In fact, this insight inspired me to ask the question According to soul sleep adherents, if unclean spirits can be conscious without bodies, why can't human spirits also be conscious without bodies?
However, the implications become interesting when we consider the fact that animals also have a "breath of life". In response to my related question Did Jesus believe in ghosts / disembodied spirits?, user Dottard made a very good point in his answer:
2. Human beings and animals appear to be a body plus the breath of life
Gen 2:7 - Then the LORD God formed man from the dust of the ground and breathed the breath of life into his nostrils, and the man became a living being [literally, "soul"]
Animals have exactly the same constitution, see Gen 1:30, 6:17, 7:15, 22, Job 12:10, etc. For example, Eccl 3:19 -
For the fates of both men and beasts are the same: As one dies, so dies the other—they all have the same breath . Man has no advantage over the animals, since everything is futile.
If humans and animals are essentially made of the same basic components (body + breath of life), then it would stand to reason that, if humans remain conscious after death, then animals also remain conscious after death.
Do believers in post-mortal consciousness agree with this conclusion? Do animals also remain conscious after death?
