Alien features - What would they look like. The building blocks of life give us a clue.
Thousands of years ago we were walking on all fours, then a wonderful thing happened to us - we stood up. When we did, two hands became free to hold things, study things and build things. Knowledge was passed from one generation to another and the industrial revolution began.
Pause for a moment and think of the hundreds of things you do with your hands every day, and how your mind is consentrating as you are doing them. So it was our hands that made the difference. This is how our brain developed and is still doing so to this very day. Computers are turning us into cybermen.
But hands are only part of the building process, we must be able to see what we are doing as well. So how many eyes has evolution provided us with and why. To find the answer, scientists studied thousands of different creatures, the animals, the birds, the insects and the crawly things. To their microscopes they went, down, down, and everything has two eyes. Two are in focus, one does not have a backup system, and three are not required. But where has evolution decided they should be, and why.
Here we have evolution in its finest form and in true theory of reason. If our eyes were on our toes we couldn't see over a brick, and on our knees we couldn't see over a sinktop, but if they are on the highest part of our body we can see the mountains beyond.
Beside our eyes are our ears, nose and mouth, and close behind is our brain, for we are but mortal creatures and must be able to defend ourselves. We must be able to see danger, hear danger, smell danger and taste danger. Everything must be close so the danger signals can travel the shortest distance to our brain for instant reaction. Everything must be in a module says evolution, at the highest part of our body where the eyes are - we call it a head.
Now lets see about that said the scientists, and they did. Those creatures we can see, those we cannot, and everything has a head, every single one of them, moulded by the building blocks of life. This is why we loo k the way we do.
Worms have no eyes only because of their burrowing nature, and there are fish at the bottom of our deepest oceans that have no eyes because of tremendous pressure, but have two round bone indents where eyes would be.
Because the building blocks of life are abundant in the Universe, theory of reason tells us that there are basic trends in evolution. Aliens on other worlds may have heads four inches taller than ours, crammed with knowledge through the ages, but somewhere along the line they must have stood up, and from there their evolutionary path would not be much different from ours.
It is possible that intelligent alien civilizations may have evolved billions of years before us, so why have we not had a visit? Because they would be mortal creatures just like us. Distances are so vast that mortality would defeat them.
If we say that a lifespan on Earth is 80 years (three score and twenty) and we travelled across our galaxy from one end to the other at the speed of light, then 1,250 such three score and twnnty's would take place with life and death, before someone got there. - 100,000 years.
If you began your journey 2,010 years ago (at the birth of Christ), then by now you would have travelled 2.01% of your intended distance and would have another 97,990 years to go, at the speed of light.
But if alienns did arrive at our solar system they would be peaceful for their species would have survived what our nuclear armed world is going through at the present time, mastered the art of global unison and evolved into the time of future man.
In centuries hence, so will we.
