This is an abstract, philosophical idea that I initially considered absurd. I'm still not sure I believe it. But what if it were? Whose idea would we be? And what are the terms of that changed existence?
Again, I found this idea hard to believe. But it led me to consider statements the Lord has made about intelligences. There is no evidence that people were 'intelligences' prior to their life in the spirit world, despite the frequent mention of that idea in priesthood meetings worldwide. At best, we can refer to Abraham chapter 3, where the Lord refers to the intelligences of the premortal world but clarifies in the same or following verse that those to whom he was referring were indeed spirits.
Regardless of the form of the people in the premortal meeting mentioned in Abraham, the Lord was referring to them, to many of us, as intelligences. In Doctrine and Covenants 93, the Lord says that the "glory of God is intelligence, or in other words, light and truth." Is that us? Are we the glory of God?
If so, then intelligence would not only refer to our pre-spirit, premortal condition, but it would refer to each of us all of the time. It wouldn't be that we were intelligence, but rather that we are, and we bring glory to God inasmuch as we choose to live a life of light and truth.
I'm not sure how things play out with the chemistry. Perhaps we are a piece of some intelligence, or perhaps that analysis is thinking too much. Thoughts?
