How, then, did this happen? Most proponents of his outside-seeding of life, called [[panspermia]], suggest that the [[comet]]s contain the seeds of life within their tails, and the earth acquired these seeds by passing through a comet's tail. Dr. Crick and his colleague [[Leslie H. Orgel]] assumed something far more radical: that an advanced [[civilization]] built and launched a brace of intergalactic [[ballistic missile]]s, each laden with bacteria and blue-green algae, in all directions from their homeworld. One such missile crash-landed on earth, and all life on earth is the by-product of the payload of that missile.

But this begs one of two questions:

But this prompts two questions:

#Where did life originate, that it would then infiltrate multiple cometary tails?

Unless an eventual origin of life is proposed (on another planet or in space), then for each step, the observer must ''regress'' one age into the past. The problem is that he never stops regressing. ''An infinite regression cannot have an identifiable first cause.''
