Your poem reminds me so much of a verse from the Ṛg Vedas (10.129), the Creation Hymn.
Hymn 10.129 The Creation Hymn (Nāsadīya)
1 “There was neither non-existence nor existence then; there was neither the realm of space nor the sky which is beyond. What stirred? Where? In whose protection? Was there water, bottomlessly deep?
2 There was neither death nor immortality then. There was no distinguishing sign of night nor of day. That one breathed, windless, by its own impluse. Other than that there was nothing beyond.
3 Darkness was hidden by darkness in the beginning; with no distinguishing sign , all this was water. The life force that was covered with emptiness, that one arose through the power of heat.
4 Desire came upon that one in the beginning; that was the first seed of mind. Poets seeking in their hearts with wisdom found the bond of existence in non-existence.
5 Their cord was extended across. Was there below? Was there above? There were seed-placers; there were powers. There was impulse beneath; there was giving forth above.
6 Who really knows? Who will be here to proclaim it? Whence was it produced? Whence is this creation? The gods came afterwards, with creation of this universe. Who then knows whence it has arises?
7 Whence this creation has arisen — perhaps it formed itself, or perhaps it did not — the one who looks down on it, in the highest heavens, only he knows — or perhaps he does not know.
