Advanced Robots and Machines as Extraterrestrial Intelligences
Are there extraterrestrial intelligences or spacemen? However, they must not be a kind of living organisms but robots or machines.
The diameter of the Milky Way Galaxy is about 100,000 light years. Probably, no living things in the universe can live 100,000 years with the ability of traveling at the light speed. But advanced robots or machines can live a million years or their memories can be easily conveyed by other versions of robots or machines.
For the human beings on the earth in this solar system, the nearest solar system is more than 4 light years away. It is impossible for men to travel to the nearest solar system during their life time. If they travel to other solar systems to find other earths where intellectual living things live, it would take time for 1,000 or more generations of them. But one generation of advanced robots or machines might function and live in the time needed for interstellar travel.
Advance robots or machines invented by spacemen or living organisms in another planet of another solar systems, if any, would live and travel in the space for 1000 years or more through their generations or versions. But probably, living orgasms in another planet cannot live such a length of life, as implied by us, the humankind.
So, if we should encounter extraterrestrial intelligences, they must be advanced robots or machines, which means that we will meet advanced robots that were created and built, say, more than a million years ago by living things in another planet in another solar system that might be already extinct.
If there had been such living things in the universe, they should have created advanced robots that would reach the earth over space travel taking, say, a million years.
But as we have not yet found, in the space around us, any signs and traces suggesting any trial for contact with us, it is likely that we are the only advanced intelligences, probably, in the Milky Way Galaxy at least in these one million years.
However, in other word, we, the mankind, will crate and build advanced robots or machines that will make interstellar travel without minding how much it will take to reach another earth in another solar system. And these advance robots or machines will appear before another mankind in another planet as extraterrestrial intelligences. But by such time, we, the mankind, might perish.
It will not be any living organisms that will conquer the universe but advanced robots or machines. And we, the mankind, might be now marching the way to the status where finally we, living things, will be taken over by advanced robots and machines. And even after the end of life time of the species of our mankind, advanced robots and machines will go on making interstellar travel.
The matter at issue is how these advanced robots and machines will find and revere the God.
