Organic Photochemistry

Some chemical reactions take place by the action of light. These are called, "photochemical reactions", or "photolysis". Mechanistic organic photochemistry is the aspect of organic photochemistry which seeks to explain the mechanisms of organic photochemical reactions. The absorption of ultraviolet light by organic molecules often leads to reactions. In the earliest days, sunlight was employed, while in more modern times ultraviolet lamps are employed. Organic photochemistry has proven to be a very useful synthetic tool. Complex organic products can be obtained simply. Over the last century and earlier an immense number of photochemical reactions have been uncovered. — Wikipedia

As you can see, if the Wikipedia article is accurate, "complex organic products" can be obtained using ordinary light shined on what I believe is a mixture of simpler molecules.

Could advanced alien civilizations have perfected the processes of organic photochemistry and broadcasted electromagnetic radiation in the form of, say, radiowaves, etc. tuned to frequencies that stimulate life-creating molecules such as proteins and DNA on suitable planets like ours?

Space colonization could be rendered possible without having to build spaceships, developing life-support systems, etc. All we would need to seed the galaxy would be knowledge of what kind of electromagnetic radiation and what kind of frequencies/wavelengths would kickstart basic life-originating chemical processes on habitable planets.

Is there a geologic record around the time life is thought to have begun on earth that indicates [massive] radiation of some kind?

Solar Radiation & The Emergence Of Life

NB:

The scientific consensus seems to be that life evolved roughly 3.5 billion years ago. The universe began in the Big Bang approximately 13.8 billion years ago.

The first galaxies formed 13.7 billion years ago.

That means if an alien EM wave did create life on earth, the maximum age of this signal would be 13.7 - 3.5 = 10.2 = approx. 10 billion years old. Since the signal is traveling at the speed of light, the maximum distance of this signal from earth is 10 billion lightyears.

The oldest known galaxy, the perfect candidate for life to have first arisen in, evolved into advanced intelligence and mastered photochemistry to the point of being able to induce living molecules elsewhere in the universe by broadcasting encoded EM waves, has been given the sobriquet Cosmic Ring Of Fire and, most importantly, is around 10 billion lightyears away.

Is this a coincidence?
