All things fall into one of two categories. Things that are intentionally caused by design and plan and things that are the result of happenstance minus any plan or intent.
Theism is the claim a transcendent being commonly referred to as God intentionally caused the universe and intelligent life as opposed to the claim no intent or Creator was necessary and all came about by happenstance.
F1. The fact the universe exists.
If it didn’t exist theism would be false. The belief the universe was naturalistically caused would also be false. This fact makes the claim God did it or Nature did it more probable. I don’t know of any fact that supports the claim the universe had to exist.
F2. The fact life exists.This is where theism and naturalism part company.
Life is a requirement for the claim theism to be true as defined above. It’s not a requirement of naturalism that life occur. If we could observe a lifeless universe no one would have a basis to claim it was intentionally caused.
F3. The fact intelligent life exists.
It’s a requirement for theism as defined above to be true that intelligent life exists. It’s not necessary for the claim we owe our existence to mindless natural forces that it caused sentient autonomous beings. At best that was an unintended bonus.
It’s not a requirement of the claim our existence was unintentionally caused by natural forces that a single condition necessary for life obtain. If we observed a chaotic universe minus any life, no one would claim that universe was intentionally caused. Such a universe would be completely compatible with its source being natural causes.
F4. The fact the universe has laws of physics, is knowable, uniform and to a large extent predictable, amenable to scientific research and the laws of logic deduction and induction and is also explicable in mathematical terms.
F5. The fact that in order for intelligent humans to exist requires a myriad of exacting conditions including causing the ingredients for life to exist from scratch.
These conditions are so exacting that many scientists have concluded we live in one of an infinitude of universes. If I had any doubt the universe was extraordinarily suited for life, the fact many scientists (astronomers and physicists) conclude it would take an infinitude of attempts convinces me.
Please note I’m not listing premises or making any arguments from the gaps of our understanding. I’m referring strictly to known thoroughly established facts. It also doesn’t prove God exists. It provides reason and evidence to believe theism is true. I’m open to competing facts that make naturalism more probable.
