Life here nothing special.....prebiotic molecules in interstellar space

[Peter Lemkin]

This fits neatly with the panspermia theory of Sir Fred Hoyle, Francis Crick, and Leslie Orgel.

Hoyle's was rather unique. He suggested that it not only happened once to 'seed' life here on Earth early in its inception, but that regular 'inseminations' of new DNA in raw form or in bacterial spores or as viruses/prions in comets and and meteorites were the cause for some of the evolutionary changes in the early period of evolution [which was the greater length period of evolution - larger, more complex forms of life taking up the smaller end period].

Not long ago Hawkings was asked about this matter and while he believed there were many advanced civilizations 'out there' [by the way, simple calculations shows that if there are any, most are FAR, FAR, FAR more advanced than we are, technologically], but he felt for reasons I'm not aware of that the majority of them would be hostile and exploit Earth if they came here and contact should be avoided or at least not desirable. Others think that those advanced civilizations 'out there' that were malevolent mostly destroyed themselves or each other and really long-term intelligent life is primarily benign. Cue in Kubrick.
