I’m not even recommending that you click on the link I’m providing here, unless you’re seriously into that thing, and you might be, I don’t know, but to me it seems like an over-rated line of speculation.
Of course, it’s science, and every new bit of knowledge helps us to put together the whole puzzle, so I am glad scientists are exploring that angle, but the way it gets reported, every couple of weeks it seems, is as if it will have a huge psychological impact on mankind to find out that there was life on Mars 100 million years ago.
It won’t. If it happened, it happened a hundred million years ago. There is no current civilization on Mars, there are no people we can talk to. When we say we are searching for life in the universe, we do not mean some place that had it once upona time, we aren’t talking about bacteria embedded in comets, we are talking about bipedal creatures with huge eyes, slick skin and no genitalia. Aliens.
There are some who theorize that all life on Earth originated from bacteria or something that was comet-borne. That is even less relevant. We are primates, descended from primates, but we keep other primates in zoos. If we’re not even treating our nearest co-descendants as equals, imagine how much less people are going to care if it is proven that life on Earth originated off Earth. That was microscopic life, that life had no connection with our life, seemingly.
What’s important is that that life, this life that we are blessed with, evolved on Earth, in symbiosis with this planet. We are earthlings. Whatever our origin.
