Astronomers for centuries were waiting expectantly for a glimpse under the clouds of our sister planet, Venus. Theologians believed for a time the biblical “new heaven and new earth,” (Revelation 21:1) might be the solace promised. They viewed it expecting in their minds to see doric columns and flying cherubs, playing harps.
When the spaceship Venera 4 penetrated the clouds of Venus in 1967, it is rumored that the surface temperatures, hot enough to melt lead (averaging around 467 C), indeed rendered the Russian spacecraft a smoldering waste within minutes.
Fifty km above the ground, Venus cloud is a balmy 25 C and 1 atm, perfect for any spores hitching a ride from Earth to pop off and begin terraforming.
Venus cloud is full of carbon dioxide and sulfuric acid - essential components in bioterraforming.
Water is a byproduct of bacterial biochemistry under certain conditions. Is the ocean not mere chance but the spore’s work?
After enough water is gathered in vapour rains begin. The melting hot surface is enveloped in a dense fog. Shallow pools might form. In time some of the spores move into these warm little ponds.
DNA stored within - previously viewed as “junk”, is deployed to bring adjustment about, another level. Lightning storms add energy to the mix and accelerate mutation.
More complex forms evolve or rather - are deployed. A symphony in God’s little bag of tricks.
Statistics on the pure “chance effect” of mutation as presently observed resulting in the change from amino acids, (which spontaneously assemble as Miller and Urey discovered in 1953 by adding electricity to a soupy mixture of hydrogen, steam, methane & ammonia), to archaean bugs to humans in so short a time as 3.5 billion years, suggest a different tune.
With the vast majority of mutations seen in petri dishes being harmful and not adaptive, it is estimated that for such rapid change to be seen might take trillions, not billions, of years.
Fred Hoyle, who discovered Uranus - and wanted to name it George, after the emperor of Britain - postulated that life on Earth began predesigned by way of spores. Panspermia, now refined to Directed Panspermia, seemed one way to explain how DNA and proteins somehow came into being by way of chance in a cell in so short a span.
