Not really. AI isn't intelligent by any stretch. To make that claims requires ignorance of what constitutes "intelligence", especially the most essential element of intelligence, viz., intensionality. LLMs or expert system or whatever absolutely lack intensionality by definition because computation is by definition a purely syntactic process.

I think you're way out of your depth here and making things up. The first tell is that you use "religion" as a blanket term as if all religious traditions make the same claims, which they absolutely do not. You can discredit, say, Mormonism much more easily than, say, Islam (though, ironically, there is a strange structural similarity between the two).

> we will be able to answer with 100% certainty that we are not alone or unique in the universe since we recreated life [..] so why not across the billions and trillions of other planets out there?

Who exactly claims that human beings or, generally, life on earth is the only life in the universe? None of the major religions do. I'm also going to assume that Christianity (or some caricature of it) is for you the paradigmatic reference point of what constitutes "religion", in which case there is nothing in Christian theology that excludes the possibility of life - even embodied intelligent life - elsewhere in the universe. (The latter is actually interesting from an ontological perspective. If the definition of "human" is "rational animal", then by definition, all rational animals are human. So, from an ontological perspective, even if an intelligent, phylogenetically distinct species were to be found on another planet, ontologically, they would also be human.)
