This thread should have ended here. Not to mention the fact that you can't force yourself to believe in something.
I think you hit the nail right on the head.
I can't force myself to believe in something. It is impossible. Either something truly miraculous has to happen to me or it doesn't. If it does, I change my whole worldview instantly. If it doesn't, talking for hours about it surely isn't going to help. I realize this about "religious debates", they are just for light chitchat. I enjoy talking about it myself, but I know it is just for fun, nothing serious.
How can words change anything? ...
I have an opinion that such discussions are limited hopelessly by the grammar, as might have been discussions about math in an Indian tribe whose set of words for numbers were "one, two and many."
The central question is whether the universe, or the local subset of it if one wishes, is intelligence/consciousness rich or intelligence/conscious poor. There is no need to limit this to biological creatures, it's an abstract discussion. If it is
"poor" there is a question where that is caused a speed of light limit on communications.
In the first case, there would be massive sentience; in the second, something like oasis of sentience in vast deserts. But these things have had billions of years to develop, there have been several generations of stars.
Today it is popular to ask when we may create super-AI, but the above indicates it's likely been around a very long time. Somewhere, perhaps not here. Whatever one wishes to call such a thing. Charles Stross used a phraseology "weakly God-like."
Clearly this is a different, more detailed and more nuanced look at the matter than monotheism would argue, but it argues neither for or against monotheism. However, I can't fathom why any one would waste time worrying or debating the existence or not of a god, when the existence of sentience outside and beyond humans had implications that at least partly address that question.
Why? Because it's not just going to be a few ET types. It will be the entire range of life, such as what we have here, plus the things that are yet to be developed here but pretty much certain, such as AI and super AI. And given the known age of the universe and the star systems, that AI will have been developed not for fifty or one hundred years but millions or billions of years.
