talk about some far-fetched sense : on the origin of life on Earth
---
To state the obvious, the human brain is the most powerful natural brain on earth. It is curious that being the #1 top-performing brain in the world, it has a very big gap in terms of the things that it can do over the #2 brain on the animal brain list. Assuming that there has been a fair game of developing different types of brain from the same set of resources, one can say that the game's current state is highly anomalous. The human brain is a quintessential outlier relative to the set of naturally thriving brains today. Adding more damage to this almost "whitewash game" is that this brain is capable of designing artificial brains (i.e. A.I.). The development of these factitious brains tries to match what the natural human brain is capable of, or even surpass it.
After many years from now, mankind maybe capable of transporting these brains to other prospective worlds in space; and if these are "ultra sophisticated" enough, e.g. self-replicating and capable of evolving on its own under the environmental conditions where it is designed to thrive (yes, designed; i.e. ensuring with the highest possible probability that a biological system will still develop under the harshest possible factors in that alien world, e.g. self-assembling lego parts to create different "living" creatures - somewhat an open-ended result as long as the lego parts keep on thriving), then a different biological system will develop in that world, not necessarily similar to that of the Earth as we know it. Think about a chain reaction of artificial brains landing on different worlds in the universe. A brain that developed in a certain world has evolved into something that is capable of creating another brain and then might be interested to propagate it to another alien world. In this case, this is even beyond what Star Trek or Star Wars has depicted. That chain reaction is in itself a quandary, and borrowing terms from mathematics, each brain should still have an "origin" for that "chain line" (from the "number line"). Think about the number line. What is considered to be observable is just a portion of that line; but then the other portions are not necessarily falsehoods, and they cannot be even dismissed in an instant as non-existent.
