I try to avoid conspiracy theories and fringe science, but every once and a while a story catches my attention and I read on past the crazy headline. Such was the case with a story that says “Humans Could Be From Venus: A theory about the destructive nature of humanity”
Even if your only knowledge of Venus comes from an elementary school science class, you would know that the planet is not for humans. These days we hear about Mars expeditions, not ones to Venus.
The atmospheric pressure on Venus is high enough to crush humans. The air is a toxic mix of sulfur and carbon dioxide. The temperatures on the surface is hundreds of degrees. So why would anyone think that human life might have been there at one time?
It is actually connected to the idea (and supported with money by people like billionaires Jeff Bezos and Elon Musk) of a future for the human race off this planet on Mars or beyond. Might the human race have done this move before?
NASA, in looking at our own climate data and worst-case scenarios for the future of Earth, has pondered whether Venus might have once been habitable and that its ecosystem was destroyed. Those scenarios about Earth’s future has a planet more like Venus.
The standard theory on Venus is that natural planetary causes or an event from space created the planet we know. Is it at all possible that humans or some form of ancient human ancestor millions of years ago destroyed the planet? It’s the greenhouse effect unchecked. More CO2 goes into the air and heat gets trapped, temperatures rise which causes more CO2 to be released into the atmosphere and that loop eventually destroys all life.
I doubt that is what happened. This is where the speculation gets pretty crazy in a way that is good for science-fiction plots but not for science non-fiction. Where is the evidence for this Venus theory? I don’t see any – but others do.
Following this Venus line of speculation leads us to ask how and why did humanity make a quite sudden evolutionary appearance on Earth relatively few thousands of years ago? The whole primate to primitive humans to fully homo sapiens has had scientists theorizing for centuries. Having us land here from Venus is an easy (too easy) explanation.
And then we get to all the ideas about things like Stonehenge and the Great Pyramids and agriculture which all arrive at roughly 3000BCE. The theory that has produced lots of books and movies has been that aliens visited Earth and helped humans leap into the future. But what if those “aliens” were us come from Venus?
Venus now is completely uninhabitable. It has a cloud cover so thick as to prevent us from getting a closer look at even the surface. That ambiguity allows the Venus-was-our-home theorists to wonder if under the clouds and surface there might be the remnants of an old civilization. We start out on one planet, flourish for a few thousand years, and eventually ruin the place and then move on to the next one.
It makes for an interesting story. It’s a cautionary tale about what we are doing – and maybe have already done before – to a planet’s environment.
I just wonder why those Venusians who were advanced enough to make it to Earth ended up being so primitive when they got here that they needed to start over. Didn’t they bring any of their advanced tools and records? And why did they look so primitive?
I think I’m seeing more credibility in the old aliens-helped-us theory from the 1950s. If that one is true, they should be arriving again pretty soon to move us off Earth to the next place.
