As far as the H to He through the C12 cycle “known by thermonuclear fusion” where is the 5 billion years of data that we have from following this cycle from start to finish stored? The answer is that we do not have this data...again making assumptions that because a certain element is present that it had to go through a certain process. These elements could have been in the original created sun, my point is that we do not have a sample of the original sun to work with so we can not empirically test it as to what elements were present when it came into being. With out the ability to test the original, any age given to the sun, earth, milky way, etc would be based on an assumption and thus can not be proven through the scientific method because the final part (testing) can not take place. This would be for both young and old earth people.
Please do not think that everything is set by what we currently observe...
2 Peter 3:3-7 To begin with, you must know and understand this, that scoffers (mockers) will come in the last days with scoffing;[people who] walk after their own fleshly desires and saying, Where is the promise of His coming? For since the forefathers fell asleep, all things have continued exactly as they did from beginning of creation. For they wilfully overlook and forget this [fact], that heavens [came into] existence long ago by the word of God, and an earth also which was formed out of water and by means of water, through which the world that then [existed] was deluged with water and perished. But by the same word the present heavens and earth have been stored up (reserved) for fire, being kept until the day of judgment and destruction of the ungodly people.
Again, we are testing things that are in the present and then assuming things about the past based upon the present data, this would be assuming that “all things have continued exactly as they did from beginning of creation”.
I would agree that science and God need to be studied but I will not put science over God or His Word especially when the science cannot be tested.
So as to throw us off? There's no demonstration to that end. But okay for you.
