Hi rick,
Well, the most glaring would be all the evidence provided through the earth sciences that would cause one to believe that the earth is old, i.e. several million or billion years vs. one who looks at that same evidence and believes that the earth is young, i.e. less than 10,000 years in existence.
Young earthers believe that the first statement of truth is what God has told us. Anything that scientists would introduce as evidence that contradicts the first truth is in error. Now, I can't honestly say 'why' it might be in error. I can't point to a decimal point and say, "Oh, see here, this decimal point is in the wrong place and that's why you're getting bad answers." For me, the answer lies in our ability to be able to truthfully prove anything about the distant past.
Let me expound. The proof that the scientific community that believes in an old earth use aren't really proofs in that they can be repeated and are testable on the matter involved. Let's deal with the matter of the speed of light. We can today test a light source and determine the speed at which new light from that source travels away from the source. We can, therefore, say that light today travels at such and such a speed. We can look at someone's similar measurement of the speed of light done 50 years ago and also conclude that light traveled at the same speed then. But we have no way of proving that light traveled at the same speed 200 years ago. The best we can do is to assume that the speed of light is a constant and therefore determine by the definition of something that is a constant, that light has always and forever traveled at the speed we measure today. But we can't prove that! We can only agree to believe it based on our now establishing the speed of light as a constant.
But, as is often the case, science then goes out and shoots itself in the foot. Now we seem to be finding a plethora of evidence that is going to pull the speed of light out of this group defined as 'constants'. We now have astronomers telling us that there are certain conditions under which the speed of light does vary. Uh-oh. Now what becomes of all those 'proofs' that we believe we have proved that were based on the speed of light being constant?
All measures, let me repeat with emphasis, ALL MEASURES that we make today to use to prove time in the past are based on these 'rules of constancy'.
Finally, science, by it's very nature will not allow any explanation for something to be..."It's a miracle!!!" How did the ground move in California that caused things to shake and fall? It's a miracle!!! No, science won't accept that. Science is based on the 'assumption' that everything has a natural cause.
There's a streetlight on my corner because some road department went out there an installed it. It didn't just appear! And for the things that man does, this is true. Man cannot perform miracles. But God can!!!!
So, God might well have created all the heavens and the earth just as He said He did and stretched all the light of all the stars to encompass the whole of the universe at the moment of its creation and from that instant on...light travels at the speed we measure it to travel. That would be a miracle, wouldn't it? I have full faith and confidence that in anything in which God has made a claim to have done something, where man says it just can't be done, I'm going with God. In every case where God has made a claim that He has done something, but man says, well it couldn't have been done in the time that God said. I'm going with God.
God has said that He created the heavens and the earth and all that is them in six days. God has said that on the sixth day of that period that He created man. God has said how old, in years, Adam was when he had his son Seth. Then continued a fairly concise genealogy through to Abraham. He then gave us some reasonably precise clues throughout the Scriptures that we can know how long it's been from Abraham until today. All of God's evidence, as I understand it, points to this created realm having only existed for about 6,000 years.
However, the deception regarding the age of this realm in which we live is strong. We do so want to believe what people who have given of so much of their time and energies and monies to learn and study the natural processes of the creation tell us is the truth! But God has been clear that His righteous ones will live by faith. Not by the proofs of men.
So, let's go over some of the scientific proofs of the things that God has said that He has done and what man's science has proven. What do we have on turning the shadow of the sun back the distance of 10 steps? Has science been able to prove or disprove that? What do we have on the sun shining brightly in Goshen, yet for three whole days it being so pitch black that one could hardly see their hand in front of their face? Has science been able to prove or disprove that? What do we have on a woman becoming pregnant without ever having sperm introduced into her egg? Has science been able to prove or disprove that? I'll start with those few. If you have answers for even them, then we'll move on with others.
Ok, you got a response. The balls in your court.
God bless you.
In Christ, Ted
