**What I don’t understand is why you give power and intelligence to the many things that surround us, but not to the universe as a whole? Paganism seems to give credit to the individual things in creation, but not creation itself. **
I have had neither an experience with "creation itself’ speaking to me nor convincing evidence of a singular deity. I have had and heard, from people I know and trust, of experiences such as mine with various Gods (including those identified as polytheistic and monotheistic). I see no compelling reason to believe that they are lying to me about having those experiences, including Christians, but I also see no compelling evidence that the experiences the monotheists relate are in any way qualitatively different from those of the polytheists or unique, so that gives more weight, to me, to the argument for polytheism rather than monotheism.
**If you don’t mind me asking, could you share an experience you have had with your gods? (it’s okay if you don’t want to, I’ll understand) **
Nothing spectacular (frankly, I am always a bit skeptical of claims of huge spectacular miracles, etc from anyone, and, yes, that definitely includes other Neopagans

--I’m probably harder on them in these terms than I am on those from the more established religions). No flashing lights, no parting of the heavens, no physical manifestations.
I imagine that most folks have similar stories–the experience of a feeling of Presence, of power at various times in specific places associated with the Gods, things running more smoothly after pouring libations to Hermes for a journey, experiences of an understanding of peace and support. Life simply runs better, and I am a better, stronger person in my interactions with others. Things happening or appearing just when I need them, sometimes after having prayed about them or performed libations.
One in particular that struck me–we were at the beach about 3 years ago and, after we had poured our customary libation to Poseidon, my daughter, age 3, wanted to build an altar to Athena in the tall grass at the edge of the sand (she has always had an affinity to Athena, which surprised us a bit as it is usually Artemis who is associated with the protection of children). She did so and happily visited it with shells, etc during the next couple of days as well as reveling in the water. The next day, while she was playing in the surf, a black shell with a hole in it perfect for stringing as a necklace washed up at her feet. She was very excited and we talked about being grateful to Poseidon and saying thank you for the gift. We told her we would go and get some cording at the store so that she could wear it. As we walked back, we passed her Athena shrine and, laying in front of it was a black cord of just the right size and length to be a necklace for our daughter. It had not been there an hour before, as we had stopped by on our way to the beach.
I could probably do some sort of statistical analysis of the likelihood of a particular shell of this type washing up on this beach and of the likelihood of someone dropping just such a particular cord in that particular spot at that particular time if I were so inclined, but I am not. Was this coincidence? Possibly, but in the framework of my religious belief, it was, and we treated it as, a rare gift from the Gods. I found it particularly striking as the stories are definitely
not filled with examples of cooperation between Athena and Poseidon, so this is not something we would have expected at all.
Would a Christian have a similar experience (within their own framework, I’m not saying I would expect that they are out building altars to Athena or pouring libations to Poseidon

)and credit it to their God? Probably. Much of our experience of the miraculous is in the noticing of everyday things. Life itself is miraculous and so much of interpretation depends upon the framework one puts upon experience.
