I think that the first flower of life was drawn when the first human experienced a psychedelic substance. When I trip shrooms or LSD, that is the holographic pattern I see everywhere - I'm not sure about anyone else's experience? Nobody has been able to describe or draw me the pattern that they see. Although I have noticed that the geometry changes according to one's vibrational state.
I also see a tiny colour spectrum of pixels making up this pattern which first made me wonder if those circles are the torsion waves of love connecting us all as one in this illusion of things. The name "flower of life" would make sense as flowers are associated with enlightenment which would be the realization of the true human origin - and simply because that is what the pattern/blueprint of energy for life looks like.
Just some of my own musings ^^
