Francis Crick (8 June 1916 — 28 July 2004) was an English scientist who was most noted for being a co-discoverer of the structure of the DNA molecule in 1953 alongside James D. Watson.
Francis Crick Watson and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology for Medicine “for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material.”
He was clearly a brilliant scientist who unfortunately, like many other brilliant minds who came up with theories that challenged the accepted frameworks at the time, wasn’t given much ‘press.’
In his book published in 1982, Life Itself, he argues that there is no possible way that the DNA molecule could have gotten its start here on Earth and that it had to have come here from somewhere else. Within the mainstream scientific community, the generally accepted theory is that we are the result of a bunch of molecules accidentally bumping into each other, creating life. However, according to Francis, we are the result of what is now known as Directed Panspermia. Crick and a British chemist, Leslie Orgel, published their paper on it in July of 1973.
Their theory explains that, “organisms were deliberately transmitted to earth by intelligent beings on another planet. We conclude that it is possible that life reached the earth in this way, but that the scientific evidence is inadequate at the present time to say anything about the probability. We draw attention to the kinds of evidence that might throw additional light on the topic.” (source)
As far as Crick’s thoughts on the theory that we are the result of accidentally bumping into each other, he thinks this was as likely as the assembly of a jumbo jet hit by a hurricane in a junk yard. In other words, he thought the theory held little to no credibility.
