I watched the video and better understand how you connect the ark with Gen 1. I don't see it. The ark followed an Egyptian design. (Search Egyptian bark) The winged cherubim have inspired imagination for millennia. Were they the standard four-legged winged bull minor-deities that pull Yahweh's chariot or some other more humanlike form that developed later? Honestly, I suspect the ark design was inherited, and the cherubim had cultic meaning lost to the ages, perhaps as guards of the contents. In the postexilic period, many attempted to interpret the symbolism with no little imagination through a lens of anachronistic strict monotheism. The later Rabbis offered a half dozen or more theories.
In short, the design of the ark/bark was likely historically ancient (from the period of Egyptian hegemony, see Hezekiah's seal) while Genesis 1 (as it reads, not the ancient chaos elements incorporated) comes from a much later tradition and the connections you outline linking the two are not persuasive. About the only suggestions of symbolism we have in the Tanakh is1 Chron 28:2 that seems to call the ark "the footstool of our God", which doesn't describe it in a tripart fashion and probably represents an early effort to reinterpret a cultic object no longer understood.
I hope you don't take offense, I'm just giving some observations and impressions, and having fun digging up stuff I hadn't thought about in nearly 20 years.
