The first line indicates that the entire poem is about the author digging up their memories and their past. Such a structure (a single opening line and uneven stanzas) and with the right punctuation gives the poem a regimented feel. Arguably, the heart of the poem is neither the first line nor the second, but in my opinion, the first two lines in this poem are already enough to make a great poem. The idea that is presented to the reader in the phrase "giving birth to fantasies and our own religion" is mutually connected with the closing line, "were we not"as it could be seen as a direct answer. Overall, another mesmerizing and powerful poem, keep it up!
