Fire, and the light from it, represents the Lord our Father, Who is represented by the first letter and the first element (hydrogen) from which light was made on the first day. On the fourth day, the light was brought together into a physical form to represent Yeshua ha'Mashiach (Jesus the Messiah/Christ) Who is the Lord (the Son) in physical form. (Ge 1:3, 4, 5, 14, 15, 16, 17, 18, 19)

Gas/air/sky/heaven (atmosphere) represents the spiritual realm and man's intended home/tabernacle (second letter) being created on the second day from between water. Breath/wind represents (the Lord) the Holy Spirit (Breath of life) Who gives life to our earthly flesh. (Ge 1:6, 7, 8; 2:7)

Liquid water was over the surface of the earth in the beginning and is part of the physical earth (physical realm). Water was split in two parts (a tabernacle/body/physical representation) to become the physical representation of the sky that came from between the water, making water also part of the spiritual realm. Water, being neither solid nor gas, represents both the physical and spiritual realms together. (Ge 1:1, 2)

Solid land (earth), which arose on the third day, represents the physical flesh of mankind made from the solid physical earth on the sixth day. (Ge 1:9, 10, 11, 12, 13)

Fire = day 1(light made), day 4(Sun & Moon and stars made) = Lord (stars are those who are part of the Lord's family)

Gas = day 2 (sky made), day 5 (birds made) = spiritual (Ge 1:20, 21, 22, 23)

Liquid = day 2 (water divided), day 5 (fish made) = both spiritual and physical

Solid = day 3 (earth & plants & trees made), day 6 (man & animals made), (2x3  = man is tabernacle of earth) = physical = all that live on the earth (Ge 1:24, 25, 26, 27, 28, 29, 30, 31)

 day 1 = Fire, day 2 = sky & water, day 3 = earth, day 4 (physical bodies/tabernacles made to represent the fire made on day 1), day 5 (physical bodies/tabernacles made to represent the sky & to represent the water made on day 2), day 6 (physical bodies/tabernacles made to represent the earth made on day 3). Days 4, 5, & 6 are the second (tabernacle) set of 1 through 3.

Ge 1:1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31; 2:7
