The work by men like Bernard Haisch and his coauthors points to the fundamental background state (the zero point field) being the 'sea of spacetime' into which God spoke creative waves. The opening of this realm of spacetime has at the leading 'edge' a soliton of time, but within the volume of spacetime are many continuua of space and time geometries, only one of which is our '4D' realm.
I am convinced that life is ubiquitous in this realm. However, the Bible teaches me that spiritual life is not ubiquitous to this 4D realm, that it is one of the special conditions established by The Creator. I postulate that life is interwoven with the 4D realm due to the reality of a completely different dimension I call --for want of a better term-- the dimension of life force. I postulate there is also a dimension of spirit which by God's Creating can intertwine with the dimension of life force in the specially created beings, like humans/the reborn. Jesus told Nicodemus that except a man be born of water and the spirit ... it is noteworthy that in my paradigm the dimensions of life force and spirit are independent of dimensions time and space, except where intertwined with these other dimensions.
The consciousness of a living thing is sourced somewhere else from spacetime, yet uses the realm of spacetime to accumulate information and thus 'grow in Grace and knowledge.'
The earliest attributes we learn of God are that God is conscious, that God is Creative, that God is love, and that God is Spirit. Each dimension of His Creating has a means to be 'touched' by the IS of God.
All variable expressions possible in each dimension and in all the interwinings of these expressions are accessible to God but cannot bind Him. Jesus showed this by rising from the grave, because death could not bind Him. Imperfection could not resist His miraculous transformations (miracles), and limits could not defy His creative commands (feeding thousands with meager rations).
It is often asked by skeptics 'why would being so much more technologically advanced than we humans waste so much time visiting our planet?' The simplest answer is, perhaps these other beings lack something God has created in humans, namely the dimensional quality of spirit. The Big Bang brought about the initial conditions which through His Word have brought forth we and they and the Angels. But even with their abilities, Angels are inferior to humans. Jesus/The Word made flesh Who dwelt among us/God with us made Himself a little lower than the Angels to be with us. His miraculous living shows that 'less than' was not a measure of technologies, and He told His Disciples, These things I do ye shall do and greater still.'
"Light be" would be Hayah 'Or. The verb "be" is in the imperfect form, yihi which can indicate a number of things--future tense, future subjunctive, past perfect, etc.--but which the translators have (rightly, to my mind) put forth as the future imperitive. Yes, it involves interpolating in a few words, but nearly all translation from the Hebrew does, due to the compactness of the language.
Since you wanted to talk about Hebrew grammar . . . ;)
For the rest of your post, I don't have a problem with your suppositions, though they are, of course, unprovable. However, I am curious about how you are defining the terms "deep," "earth," and "waters" in the first few days of Creation, and why.

Possibly. My own take on the UFO phenomina is that it's a combination of our own cutting-edge tech (the Harrier jet used to get reported as a UFO all the time before they declassified it) and the visitations of spiritual entities in the physical realm. Those spiritual entities definitely lack something we have: They aren't native to the physical plane of existence, nor the masters of it; they don't have gender; and they can't reproduce. In fact, I would surmise that of all the beings that bear the image of God, humans are the only ones who can reproduce . . . which is why the spiritual entities are so fascinated by it.
Time to clock in for work, so until later, Shalom.
