I remember as a young child going to a magician show and on leaving the show (absolutely fascinated) asking; ‘how did he do that?’ I was told; he is not performing magic – he has a trick.’ I grew up on a farm, and my first jobs were on farms. I soon learned; if something broke down there was a reason why – and there had to be a way to fix it.
Biology is different.
A human cell has about 2 meters of DNA.
DNA molecules have a width of about 2.5 nanometres - a nanometre is one billionth of a meter.
The nucleus of a human cell has a diameter of 5 micrometres - a micrometre is a millionth of a meter.
To get a better picture of these dimensions we can multiply by a million. The DNA now has a width of 2.5 mill and is 2,000 kilometres long. 1,000 kilometres having written out on it the 3.1647 billion nucleotides on the maternal copy of DNA – the other 1,000 kilometres the 3.1647 billion nucleotides on the paternal copy. All this must fit inside the nucleus of the cell which has a diameter of 5 metres.
Now let’s shrink it all back to its original size and contemplate the process of cell division, how the cell codes for protein, how each cell knows what to code for – processes that happen millions of times in our bodies every second.
There is no trick.
So that is the very small – what about the very big?
The Sun is 1,300,000 kilometres wide and Earth is 150,000,000 kilometres from the Sun.
Reducing the Sun to one 200 billionth of its size it is now the size of a pea – (a pea with a 7 millimetre diameter).
On this scale the Earth will be a very small dot and 70 centimetres from the Sun.
Jupiter will be the size of a poppy seed and is 4 metres from the Sun.
Pluto is too small to see with the naked eye and is 30 metres from the Sun.
Alpha Centauri is the closest star and is 4.367 light years from Earth. On our reduced scale Alpha Centauri is also the size of a pea and is 208 kilometres from the Sun.

But hang on; isn’t the universe held together by gravity? Would an object the size of a pea have any gravitational pull on another pea 208 kilometres away? And what about stars and planets that are billions of light years away? And don’t astronauts, only a few hundred kilometres from Earth, float around in space with no gravitational pull from Earth? And what is it that spins Earth on its axis every 24 hours – and rotates Earth around the sum every 365 days?
It is undeniable however that something is ordering the movement of planets and stars (and comets).
Like the workings of biological systems – the cosmos is incomprehensible to the human mind.
If then we assume earth is a living biological entity, part of a living universe, it is not surprising that there is much we do not understand.
As mentioned earlier; it is likely our species and our planet is part of a greater cosmic entity. A cosmic biological entity with a germ-line that will shuffle around ancient genes in the same way our species will code for, and occasionally express, our species ancient DNA.
So greengirl, why puzzle over the ‘how, when, by whom’ of mysterious buildings and artefacts? If they are an expression of ancient DNA, the ancient DNA of a living planet in a living cosmos, we have no more hope of understanding their origins than we to our own biological processes.
