Observation, unless you personally are making these observations. Then you are simply taking another mans word that this is true.
Interesting.......Genesis was written anonymously, however, both the Christians and Jews accept that he wrote it (no argument there). Though many biblical scholars believe it was a compilation of written and oral stories that were complicated by Moses.
Having said that, does the same logic apply when reading what is now known as The Bible, do you accept Moses' (and other unknown sources) observations about the beginning of the world? Further, do you accept that it is the truth even though you did not observe it for yourself? That is why I say believing something based on faith may not be as accurate as believing something based on recorded data which includes photographs, heat scanning, and scans for differing types of radiation and light. It sounds like a double standard to say you don't believe any scientific discovery you haven't personally witnessed in real time but you would accept second and third-hand accounts (with no visual proof) of people who never witnessed the creation of Earth.
So one can believe by witness or faith. Is believing through faith a more accurate observation than believing first-hand accounts which are accompanied by visual proof?
Since mans words about God's creation do not agree with God's descriptions. I will go with God's and not try and make the two agree. I personally do not trust man and what he states is, is.
But you do trust the word of man if it is written in an ancient text correct? I'm sure you know that neither God the Father, Jesus Christ, nor the Holy Spirit used a physical means of communication like writing. Who did they use to communicate? Would that be men? Are men whose writings were included in the Biblical Canon made perfect or was that honor given only to Jesus Christ? I believe you did say "I personally do not trust man and what he states is, is." Does that include the "men" who wrote the scripts that would be included in the Holy Book of religions instruction?
Men are still men no matter what they are called to do, can we agree on that? The writer of a Bible book is just as imperfect as an honest man who flips burgers let alone a man whose sole aim is to find answers in the mystery that is the Universe. I understand that people want to be good, obedient, and faithful Christians but the physical laws of nature have been the same now as when God created light.
Now, philosophical questions that we don't have universally agreed upon proven answers are best answered by God through our chosen faith however, as currently we still live in a physical Universe where all of the laws of nature, biology, chemistry, physics, and mathematics are constant and provable, we don't need to use faith to answer those questions other than how do we apply this knowledge in the best way that will glorify God.
In other words, faith is what we use to measure our purpose, but weighs and measures is how we measure the known Universe.
Does that make any sense? I know it is your duty to say no but looking at it objectively with free will, intelligence, and understanding granted to us by God, how can we deny truth when it is physically shown to us in real time?
