Christianity IS the old Testament. Christ and the cross make no sense without Genesis. Whenever Jesus was challenged, he would refer to the old Testament as His absolute source of Truth... And he most commonly referenced the writings of Moses.
He also corrected some of the wrong things in Moses like divorce, eye for an eye and kill your enemies.
Re periodic table... It provides clear evidence of our creator. "Atoms are not chaotic in their assembly but have an orderly arrangement in the way that electrons are added to orbitals, and protons and neutrons in the nucleus. This accounts for their periodic and predictable attributes which a God of order has created."https://creation.com/atoms-and-gods-order
I tend to you agree that the precise and nearly infinite nature of the atom and the compounds formed from atoms are amazing. I just have to be honest that is your bias and my own. If you think about it, we are not scientific or logical in our thinking when we assume God exists. That is a belief of ours.
There is no scientific proof of God, and there’s no way to test it scientifically. To those who don’t believe there is a God, some of us claiming that there is does not qualify as scientific evidence, it qualifies as anecdotal evidence....which is not really considered evidence.
It’s kind of like Bigfoot, yet one could argue that there is more evidence for Bigfoot than God because of footprints, some dna evidence, and some possible photographic evidence. We don’t have that for God.
That is not to say we are wrong. I believe I’m right in believing that God exists because of my own subjective experiences. But, since I trust myself...I believe my experiences. But I don’t pretend my word qualifies for scientific evidence.
If the people who have seen Bigfoot or Sasquatch are right.....and eventually this is proven by the discovery of a body....then it does show that anecdotal evidence can be factual in some cases, and this has been shown in other avenues. But, there have been a lot of anecdotal evidence that has been shown to be fabricated intentionally or not.
