The periodic table (and hundreds of other things.)
The periodic table and everything that exists shows its nature and can be observed or understood to a certain degree. The fact that a thing is specific and precise doesn’t necessarily imply that God did it, because it is possible that there is no God and everything we think is God is a product of our own minds, superstitions, religious beliefs, etc.
That’s why I’m distinguishing scientific fact from opinion or beliefs. Yet, I’ve already stated my opinion on that point so there’s no need to say it again. You disagree and that’s fine, but I just think your point is incorrect. Things that are made don’t necessarily require a Maker.
For example, take a puddle of water from a hole in the street. That puddle of water seems perfectly designed to hold the water that fills it, and is home to billions of microorganisms. Like us they fight for survival in this world.
But there home was not designed, it is a pure result of natural forces that we understand by science and the laws of physics.
So we agree that the cause of everything existed eternally. If you don't think that evidence points to an eternally existing intelligence, you are wrong.
If you would be specific about evidence, maybe I could agree. But it seems you assume that everything that exists is evidence of intelligence, and that may not be true. Not to be argumentative but to be factual. We don’t really know where we came from or why we’re here, or where we go when we die. We think we do. And we all think differently about it so no one really knows.
I agree that things which are have the appearance of existing eternally, and indicate the real possibility of supreme intelligence. Yes, I agree. But I don’t believe it can be scientifically proven because of the nature of science that requires observation to be highly confident about a thing....in general.
Einstein’s solution to the red shift of mars all happened in his mind. But his theories later held up under experimentation and observation.
