This article is just as much for me as it is for proving that The Bible contains scientific facts. Sometimes I forget some of the things that The Bible says or I forget the number of verse so this will prove to be an serviceable resource in the end. Anyway to begin with I shall list some of the scientific facts contained within The Bible proving that it isn't unscientific or irrational:
The Universe Had a Beginning:
Genesis 1:1 says that God created the heavens (the universe). This is contrary to the claims that some scientists made before it was discovered that galaxies were moving away from each other supporting the idea of an expanding universe which in turn suggested that all matter came from one place which implied a creation event. This evidence backed up Georges Lemaitre's Big Bang theory which states that all matter came from one single point and which also explains what happened after the first few seconds of the beginning of the universe.
Germ Theory of Disease:
For years scientists came up with different theories concerning how germs were spread. Eventually theories such as the miasma theory were replaced in the 1800's by the Germ Theory of Disease when scientists discovered what The Bible said about germs was right all along and that microorganisms which originated from outside the body were infectious and could cause diseases. Meanwhile The Bible spoke of this all along and told one to follow sanitary practices to avoid diseases and illnesses.
Numbers 19:3-22, Leviticus 15:1-33
Leprosy is Infectious + Proper Quarantine Methods:
Once it was believed that leprosy was hereditary or a curse. Scientists later discovered in the 1800's that it was infectious and spread by infection which confirmed what The Bible was saying all along about leprosy being infectious. The Bible even gave commands to burn the clothing of a leper so that the disease couldn't spread (a method also applied to other diseases and illnesses). Meanwhile they were told to wash themselves and go into quarantine to prevent the spread of the disease. Also The Bible gave commands to burn anything else that a leper came in contact with because leprosy can spread on surfaces.
Leviticus 13:45, Leviticus 13:52
Laughter is Medicine:
King David wrote "A joyful heart is good medicine, But a broken spirit dries up the bones" and now science has discovered that laughter is indeed good for your health and well-being as it releases endorphins in your mind.
The expanding universe is evidence for The Big Bang theory and also evidence of creation. The Bible says that the universe is expanding and said so years before astronomers and physicists saw this to be true.
Isaiah 45:12, Jeremiah 10:12, Jeremiah 51:15, Job 9:8
Earth Suspended in Space:
There have been many different concepts of the earth throughout history. One was that the earth was held up by pillars while another was that a turtle/elephant held up the world. Eventually scientists proved that the earth and other planets were indeed suspended in space just as The Bible says.
Earth is Round + Orbit Around Sun:
The Bible taught that the earth would receive light on one side and darkness on the other clearly teaching that the earth was round and revolved around the sun.
Life only Comes from Life (Law of Biogenesis):
Many people - scientists included - one believed that life could come from non-life. This theory was known as spontaneous generation (and has re-emerged with a new model called abiogenesis). In 1858, Rudolf Virchow challenged the spontaneous generation theory by proposing the theory of biogenesis. He stated, 'living cells can arise only from pre-existing living cells'. This theory partly explained the presence of animalcule under the microscope. Later Louis Pasteur performed an experiment which showed that life could not come from non-life and that it could only come from pre-existing life which Genesis had said all along.
Genesis 1:20, Genesis 1:21, Genesis 1:24, Genesis 1:25
All Human Life Can Trace Ancestry Back to One Woman and Man:
These two people are known as Mitochondrial Eve and Y-Chromosome Adam. These are not the Adam and Eve of The Bible from Genesis but their existence and the fact that all humans can trace their ancestry back to them validate claims in The Bible saying that humanity could trace their ancestry back to two people which skeptics previously thought impossible genetically.
Genetic Traces of Jewish Priesthood from The Prophet Aaron:
The Bible claimed that priesthood - starting from Aaron - was passed down from father to son. Genetic discoveries have confirmed that Jewish priests all share distinctive genetic traits once again validating The Bible's claims and proving it to be correct not only scientifically but historically as well. These priests can trace their ancestry back to Aaron.
So there you have it folks. The Bible isn't unscientific. Anyone who claims otherwise is lying and has never ever read The Bible. Another misconception some people have is that some of us Christians believe that The Bible is a scientific document. This is untrue, The Bible isn't a scientific document but to deny the advanced scientific facts within it would be to show true ignorance on the subject.
These scientific facts contained within The Bible show that the people who wrote it were rather intelligent as it has only been recently that some of these theories have been confirmed by science while the Bible writers knew the truth all along. Further more, books like the proverbs are still relevant today and show that society has changed little - in terms of human interaction - and provides advice of how to deal with situations and scenarios in society. Proverbs warn of us making friends in the wrong crowds as their manners might rub on us and this is shown to be true even in today's society where people get involved in the wrong crowd and then end up becoming criminals or learning bad behavior.
In conclusion, most of what is written in The Bible is confirmed by science.
