I think that rational beings can arise through evolution. If the intelligence of humans is the feature of the universe that you think demands an explanation more than anything else, why would the idea that an intelligence greater than ours existed without a cause make any sense? If something like intelligence can exist without a cause, it doesn’t need an explanation for its existence.
Hello friend,
I have to say that I can find no way to see how rational, intelligent beings can arise through evolution without a personal God.
Think about it this way. If all that exists in the universe is purely physical things, then every event is nothing more than the result of collocations of atoms (to use Bertrand Russell’s phrase). If that is the case, then we have no more reason to trust the arrangement of molecules in our brains than we have to trust the arrangement of sand on the seashore. Both are nothing more than the result of lots of purely physical, undirected interactions.
Also, all the things we think we know which are not physical (the laws of logic, all of mathematics, abstract truth, goodness, beauty, meaning, justice) are really just products in our physical brains of those physical interactions, and there is absolutely no reason to think that those ideas have any correspondence with reality. If we assert a perfectly physical universe with nothing more, then those ideas definitely do NOT correspond with reality, because those are not physical entities. In which case, everything that we value most as human beings turns out to be an evolutionary side-effect without any intrinsic value. But, this contradicts the entire experience and testimony of the human race, the reality and value of the parenthetical list at the top of this paragraph.
It is not true that “something like intelligence” can exist without a cause. Everything, except for the very essence of existence itself (sometimes also known as God), needs a cause. Nothing except Being itself can sustain its own existence, and so it depends on Being itself for a cause.
You ask a good question about how an intelligence greater than ours can come into existence without a cause. The answer is that Being itself is itself intelligent. Since things other than Being itself, the essence of existence, exist, then Being itself must have created them. Since Being itself creates, it must have a will. A will requires intelligence.
Also, since our intelligence is a created thing (rather, we are created things with intelligence…there is no such thing as a pure intelligence, only intelligent beings), our intelligence must find its source somewhere (again, we do not create ourselves). All things that exist find their source in Being itself (God), and so Being itself must be intelligent.
