Thanks for the explanation but the lawn sprinkler is stationary whereas the comet is obviously rattling along.![]()
I agree with you on the panspermia issue. The experts have been agreeing and then disagreeing with the theory for years. It's similar to the 'comet killed the dinosaurs' thing.

Other things include a portion of everything, but mind is infinite and self-powerful and mixed with nothing, but it exists alone itself by itself. For if it were [Page 241] not by itself, but were mixed with anything else, it would include parts of all things, if it were mixed with any thing; for a portion of everything exists in everything, as has been said by me before, and things mingled with it would prevent it from having power over anything in the same way that it does now that it is alone by itself. For it is the most rarefied of all things and the purest, and it has all knowledge in regard to everything and the greatest power; over all that has life, both greater and less, mind rules. And mind ruled the rotation of the whole, so that it set it in rotation in the beginning. First it began the rotation from a small beginning, then more and more was included in the motion, and yet more will be included. Both the mixed and the separated and distinct, all things mind recognised. And whatever things were to be, and whatever things were, as many as are now, and whatever things shall be, all these mind arranged in order; and it arranged that rotation, according to which now rotate stars and sun and moon and air and aether, now that they are separated. Rotation itself caused the separation, and the dense is separated from the rare, the warm from the cold, the bright from the dark, the dry from the moist. And there are many portions of many things. Nothing is absolutely separated nor distinct, one thing from another, except mind. All mind is of like character, both the greater and the smaller. But nothing different is like anything else, but [Page 243] in whatever object there are the most, each single object is and was most distinctly these things.[1]
Panspermia belongs in the Mad Ideas section, in my opinion. It is tantamount to saying that aliens seeded the Earth, because there is not one shred of proof for the concept.
In the early 1970s, Crick and Orgel further speculated about the possibility that the production of living systems from molecules may have been a very rare event in the universe, but once it had developed it could be spread by intelligent life forms using space travel technology, a process they called “Directed Panspermia”.[54]

Your woman O'Leary is just another modern expert who is either congenitally stupid or a liar.
Certainly, the idea is not new in scientific circles. The philosopher Anaxagoras, in 5th century BC Athens, is the first recorded advocate of the theory of “panspermia”, the idea that life on Earth was seeded from space.

The idea that life on Earth had an extra-terrestrial origin may be traced back to the ancient Greek philospher Anaxagoras, who lived in the fifth century B.C. Anaxagoras claimed that the universe is made of an infinite number of spermata (seeds). These give rise to life forms on reaching the earth. Anaxagoras coined the term Panspermia, meaning literally 'seeds everywhere', for his proposal.

The first point, which deals with the origin of life on Earth, is known as panspermia — literally, "seeds everywhere." Its earliest recorded advocate was the Greek philosopher Anaxagoras, who influenced Socrates. However, Aristotle's theory of spontaneous generation came to be preferred by science for more than two thousand years.
