The following are statements I found on the web comparing the brain with
a computer. After each statement is my question or comment:
1. Computer memory grows by adding computer chips. Memories in the brain grow by stronger synaptic connections.
(Are these connections made to unused portions of the brain?)
2. Both can adapt and learn. It is much easier and faster for the brain to learn new things. Yet, the computer can do many complex tasks at the same time ("multitasking"
that are difficult for the brain. For example, try counting backwards and multiplying 2 numbers at the same time. However, the brain also does some multitasking using the autonomic nervous system. For example, the brain controls breathing, heart rate and blood pressure at the same time it performs a mental task.
(Looks like evidence of design in both cases to me. What do you think?)
3. Both have evolved over time. The human brain has weighed in at about 3 pounds for about the last 100,000 years. Computers have evolved much faster than the human brain. Computers have been around for only a few decades, yet rapid technological advancements have made computers faster, smaller and more powerful.
(We know computers evolved by human designers. But how did the brain
evolve, if it did, on its own? Why should me believe the brain evolved without
a designer, if it evolved at all? Could not what they call "evolved" be only
evidence of us using more of our unused memory? I also can not understand
this 100,000 years and who weighed it at the time.)
4. Both need energy. The brain needs nutrients like oxygen and sugar for power; the computer needs electricity to keep working.
(Was this all by design or did it just happen that way?)
5. Both can be damaged. It is easier to fix a computer - just get new parts. There are no new or used parts for the brain. However, some work is being done with transplantation of nerve cells for certain neurological disorders such as Parkinson's disease. Both a computer and a brain can get "sick" - a computer can get a "virus" and there are many diseases that affect the brain. The brain has "built-in back up systems" in some cases. If one pathway in the brain is damaged, there is often another pathway that will take over this function of the damaged pathway.
(If a backup system is built-in, why is that not evidence of design?)
6. Both can change and be modified. The brain is always changing and being modified. There is no "off" for the brain - even when an animal is sleeping, its brain is still active and working. The computer only changes when new hardware or software is added or something is saved in memory. There IS an "off" for a computer. When the power to a computer is turned off, signals are not transmitted.
(Amazing! This just happened too, I suppose. Hard to believe.)
7. Both can do math and other logical tasks. The computer is faster at doing logical things and computations. However, the brain is better at interpreting the outside world and coming up with new ideas. The brain is capable of imagination.
(Imagiation! Did you get that?)
8. Both brains and computers are studied by scientists. Scientists understand how computers work. There are thousands of neuroscientists studying the brain. Nevertheless, there is still much more to learn about the brain. "There is more we do NOT know about the brain, than what we do know about the brain"
(How then could anyone in their right mind logically say, there was no
designer, it just happened by nature, whatever they think that is?)
