We should always first establish truth by the Bible first.
#1. Jesus referred to Adam and Eve in the beginning because he refers back to Genesis chapter 2 with the first phrase used for the first man and woman in joining together as one flesh as huband and wife. The man is told that he shall leave father and mother and cleave unto his wife.
For Jesus said:
“But from the beginning of the creation God made them male and female. For this cause shall a man leave his father and mother, and cleave to his wife; And they twain shall be one flesh: so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.” (Mark 10:6-9).
In Genesis 2, it states:
“And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man. Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.” (Genesis 2:23-24).
#2. Luke 11:50-51 says, “That the blood of all the prophets, which was shed
from the foundation of the world, may be required of this generation;
From the blood of Abel unto the blood of Zacharias,...”
Notice the passage does not talk about from the time of monkeys, or ape like men, or a pool of slime in connection to the foundation of the world. Here we see Scripture tie in “the foundation of the world” with the words, “from the blood of Abel”; Which suggests that Abel was not too far off from the time or period since the “foundation of the world” which has been laid by God in Genesis chapter 1. Evolution is an obvious deception or lie of the enemy to try and deceive unbelievers into explaining a world without God. It's so obvious. The world's way of thinking is not God's way of thinking.
#3. The genealogy of Jesus Christ from Mary's line to Adam can be traced (or read) in Luke 3:23-38.
If we are to read Scripture literally and or normally like a child, there is no real room for millions of years. For we can read about how the line of Jesus can be traced all the way back to Adam in Luke 3. I do not see a correct number of ancestors listed that would support a “millions of years type ancestory” in Luke 3, and nor do I see any mention of how there was any ancestors in Christ's line being left out, either. To say so otherwise is simply to add to the text.
#4. Death clearly happened as a result of the Fall and not before the Fall.
There is no mention of sin or death entering the world before the Fall of Adam.
Plus, Romans 5:12 says that death was a result of one man's sin (Which was by Adam).
“Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:” (Romans 5:12).
This is confirmed in the fact that God told Adam if he were to eat of the wrong tree, he would die that day (See: Genesis 2:17).
But if you believe in an Old Earth, death happened before the Fall of Adam. But this kind of thinking goes against the plain teaching of the Bible.
In fact, the belief in a Young Earth is what a normal person would have in a normal reading and study of the Scriptures. The only reason you would want to believe in an Old Earth is because of what secular science says and not what the Bible says.
Most Christians (such as myself) who stand behind the Global Flood, believe the Earth to be thousands of years in age and not millions of years old because they know the Bible and ancient civilizations to have been recorded as being only thousands of years in age. Christians also know the Earth to be young because the tremendous amount of evidence that supports a world wide Global Flood, too. In fact, this does not include the other different categories of evidences that back up the Scriptures, as well.
Anyways, when secular scientists date fossils and rock layers, they don't factor in the Global Flood into their findings. They make assumptions that the world is millions of years old and then date things accordingly. How do I know they make such wrong assumptions? Well, secular scientists had dated the findings of a recently erupted volcano to be a million years old. This means that they are biased towards dating things to be Old. Also, secular scientists claim that many rocks layers are millions of years in age, yet trees have been found growing through out these rock layers, though. Secular scientists also ignore the fact that seashells on top of mountains would have not gotten blasted away by the elements if they were sitting up there for millions of years, too. In fact, seashells on top of mountains all over the world is one of the many incredible proofs that support a Global Flood and a Young Earth. Also, there are over 270 Flood Legends all over the world (With a good portion of them paralleling the various facts within Genesis). Fossil graveyards have been found buried all over the world. Trees have been fossilized standing up all over the world. Man's denial of a Global Flood (i.e. Secular Scientists and atheists) having fulfilled New Testament prophecy (2 Peter 2:3-6); And the list goes on and on.
However, what is the real problem with Old Earth Creationism?
Well, Old Earth Creationism not only does not line up with the scientific facts but it also sides itself with Secular Historical Science (of which cannot be proven because we do not have a time machine to actually show it's real age). However, the real problem with Old Earth Creationism is that it is a model that came about from Macro-Evolution (Darwinism); And under the world view of Macro-Evolution (Darwinism) you can technically do what is good and right in your own eyes. This is called "
Moral Relativism" and it leads to chaos. In fact, under this World View: A person could say that when they murder someone, they are just one single celled organism eliminating another single celled organism by Natural Selection or survival. On the other hand, if a person were to believe in the Bible, they would be held accountable to a Creator God and a high moral code that tells them there is a right and a wrong.
Side Note:
Also, the two major theories to explain an Old Earth do not fit with a normal reading of the Bible. The Day Age Theory does not work because God defines a day in Genesis 1 as a 24 hour day with saying that day has an evening and a morning. The Gap Theory does not work because Scripture does not mention elsewhere about this Gap Theory clearly tying it in with Genesis chapter 1. To add to God's Word is dangerous and there are warnings against it at the end of our Bible (i.e. Revelation 22:18).
