I've started writing a piece about evolution. My take on it is, we are here, we live on this planet in a very thin bubble of air which is effectively a couple of miles thick, and then you've got maybe a metre or two of land underneath, and that's it. That is our environment. Out of the MASS of the universe, which numbers million, billions, of stars. Imagine that MASS! And here we are representing a tiny insignificant amount of all of that material. And all within this minuscule bubble of air, we have, roquefort blue cheese, chicken tikka, Fosters, Nepalese Thupka soup, beef, some of it crap and some of it silverside! In other words in this minuscule, thin envelopic environment we form from the around just 10 elements, Elements combined into all these fantastic things. I can't think of anywhere else in the universe you could find such things. The reason I started thinking like this is, I saw somewhere mentioned the coldest place in the universe is on Earth. With our technology we are able to create a coldness which is just not available in nature. Then I realised that there are loads of other things here that just could not be found anywhere else in the universe, probably not even on alien infested world's. But then I realised these aliens will have their own versions of Roquefort blue cheese, chicken tikka, Fosters, Nepalese Thupka soup, beef, some of it crap and some of it silver-side! Think of the trade that could be had between the two cultures.
