Fire consumes everything. So, it is considered powerful than anything else in the world.

Nimrod worshiped fire. Fire could not be god because rain (water) could quench fire. Water could not be god because water-filled clouds could be driven by wind / spirit. Wind (a form of the spirit – unseen) could not be god because spirits (evil spirits as we know now) could be controlled by humans through their Kundalini power. Again, it returns to the source of this argument – man. Could sun be god? Darkness of the night overcame it. Could moon or the stars be god? Light of the morning overcame them. Abram should have been searching for the true God who should have power over everything – Sun, moon, stars, fire, water, wind and ultimately humans. None of the creation of God could become the Creator. Period.
