Panspermia: Evidence From Astronomy to Meteorites

Towards an ethics of life

“…N.C. Wickramasinghe referred to this as the "Primordial Soup Theory [4]." As Terrence Deacon pointed out we have good evidence of emergence in some chemical processes, and it is not out of the question that we might find that life is one of the processes that results from natural emergent tendencies [3].…”

“…N. C. Wickramasinghe outlined the panspermia argument that life began somewhere else, say Mars or Venus when these planets were more verdant worlds in their earlier existence and asteroid impact ejecta from the planets drifted through space probably in an inanimate state and landed on earth where it found conditions suitable for reanimation and multiplication [4]. This is certainly conceivable.…”

“…Following the trail of panspermia theory, we must ultimately return to other theories to find life's genesis moment, e.g. emergence from natural processes or prime mover [4]. Crick and Orgel through Wickramasinghe posited that life's migration ultimately requires some form of intelligence but this still does not commit to an original genesis for life [4].…”

“…emergence from natural processes or prime mover [4]. Crick and Orgel through Wickramasinghe posited that life's migration ultimately requires some form of intelligence but this still does not commit to an original genesis for life [4]. 3 We must also consider theories that a prime mover created life.…”

“…3 Crick as in Francis Crick, co-discoverer of the DNA double helix, and Nobel prize laureate. 4 There are many religious explanations of God which I will not reference. The alien as prime mover has not received much treatment in the literature but is a common theme in science fiction.…”
