I don't think God has to play a hand in day to day physics. I think God put these things in place and set laws that they obey, like instinct for example, or gravitational pull.<quoted text>1) If you already believe something to be true, then you search for evidence to back it up you are embracing a strong bias. Science, or critical thinking, is designed to eliminate as much bias as possible. However, scientists do seek evidence to support their hypothesis, which is similar to what you describe here. But there is a powerful difference. When a hypothesis is presented to a crowd of peers and those peers do not find the evidence compelling it is rejected. A good scientist then modifies the idea or abandons it. They do not cling to it out of faith. Faith is what you have when you lack a reason. It hangs on nothing but a feeling.
2) If you accept science (particles and junk) then why tack on the added complication of a Designer? Back in Joseph Smith's day he would not have had any idea about particles. No mention of them in the BoM. No mention of quantum physics. Then along comes science and discovers these properties of the universe. Suddenly God takes on the role of being behind those properties. In fact, each time we discover some deeper fact about how the universe works you have to move God one step backward in the process. In Smith's day it would have been acceptable for an educated man to say that God keeps the planets moving and has a hand in every day life. Today we know so much more about that stuff that it makes no sense to say that. God has been pushed back to an even more remote position, always occupying that space of knowledge where humans have not yet penetrated.
The term for that is God of the Gaps. You put God into the unknown spaces. Those areas of the map that say "here be monsters".
I see your point of view, I just can't agree that the complexities that we now are able to find prove that God doesn't exist. I see it the opposite. I don't think it could have happened by chance.
