Now, there is an interesting note to take on the "heavenly fire" that fell from Heaven, based from Elijah's situation. Let's see what 1 Kings Chapter 18 states:
"19Now therefore send, and gather to me all Israel unto mount Carmel, and the prophets of Baal four hundred and fifty, and the prophets of the groves four hundred, which eat at Jezebel's table. 20So Ahab sent unto all the children of Israel, and gathered the prophets together unto mount Carmel."
"21And Elijah came unto all the people, and said, How long halt ye between two opinions? if the LORD be God, follow him: but if Baal, then follow him. And the people answered him not a word. 22Then said Elijah unto the people, I, even I only, remain a prophet of the LORD; but Baal's prophets are four hundred and fifty men."
"23Let them therefore give us two bullocks; and let them choose one bullock for themselves, and cut it in pieces, and lay it on wood, and put no fire under: and I will dress the other bullock, and lay it on wood, and put no fire under: 24And call ye on the name of your gods, and I will call on the name of the LORD: and the God that answereth by fire, let him be God. And all the people answered and said, It is well spoken."
"25And Elijah said unto the prophets of Baal, Choose you one bullock for yourselves, and dress it first; for ye are many; and call on the name of your gods, but put no fire under. 26And they took the bullock which was given them, and they dressed it, and called on the name of Baal from morning even until noon, saying, O Baal, hear us. But there was no voice, nor any that answered. And they leaped upon the altar which was made."
"27And it came to pass at noon, that Elijah mocked them, and said, Cry aloud: for he is a god; either he is talking, or he is pursuing, or he is in a journey, or peradventure he sleepeth, and must be awaked. 28And they cried aloud, and cut themselves after their manner with knives and lancets, till the blood gushed out upon them."
"29And it came to pass, when midday was past, and they prophesied until the time of the offering of the evening sacrifice, that there was neither voice, nor any to answer, nor any that regarded. 30And Elijah said unto all the people, Come near unto me. And all the people came near unto him. And he repaired the altar of the LORD that was broken down."
"31And Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, unto whom the word of the LORD came, saying, Israel shall be thy name: 32And with the stones he built an altar in the name of the LORD: and he made a trench about the altar, as great as would contain two measures of seed."
"33And he put the wood in order, and cut the bullock in pieces, and laid him on the wood, and said, Fill four barrels with water, and pour it on the burnt sacrifice, and on the wood. 34And he said, Do it the second time. And they did it the second time. And he said, Do it the third time. And they did it the third time. 35And the water ran round about the altar; and he filled the trench also with water."
"36And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word."
"37Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again. 38Then the fire of the LORD fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench."
"39And when all the people saw it, they fell on their faces: and they said, The LORD, he is the God; the LORD, he is the God. 40And Elijah said unto them, Take the prophets of Baal; let not one of them escape. And they took them: and Elijah brought them down to the brook Kishon, and slew them there."
Now, there are sources that state this to be a form of stone from which is was ignited by the many times the water was put onto the offering (though this is stated by the History Channel and Smithsonian Institute).
However, based from learning about the God of fire and His connections to the fire offerings, and so far, the "Hearth" practice as this was commanded by Him (I personally will take a chance as this power pertains to this deity). But first let's address how this similar power was done in the time of Job: Job Chapter 1:
"1There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil. 2And there were born unto him seven sons and three daughters. 3His substance also was seven thousand sheep, and three thousand camels, and five hundred yoke of oxen, and five hundred she asses, and a very great household; so that this man was the greatest of all the men of the east. 4And his sons went and feasted in their houses, every one his day; and sent and called for their three sisters to eat and to drink with them."
"5And it was so, when the days of their feasting were gone about, that Job sent and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number of them all: for Job said, It may be that my sons have sinned, and cursed God in their hearts. Thus did Job continually. 6Now there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them."
"7And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it. 8And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?"
"9Then Satan answered the LORD, and said, Doth Job fear God for nought? 10Hast not thou made an hedge about him, and about his house, and about all that he hath on every side? thou hast blessed the work of his hands, and his substance is increased in the land."
"11But put forth thine hand now, and touch all that he hath, and he will curse thee to thy face. 12And the LORD said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the LORD. 13And there was a day when his sons and his daughters were eating and drinking wine in their eldest brother's house:"
"14And there came a messenger unto Job, and said, The oxen were plowing, and the asses feeding beside them: 15And the Sabeans fell upon them, and took them away; yea, they have slain the servants with the edge of the sword; and I only am escaped alone to tell thee."
"16While he was yet speaking, there came also another, and said, The fire of God is fallen from heaven, and hath burned up the sheep, and the servants, and consumed them; and I only am escaped alone to tell thee."
I find this interesting as the "fire from heaven" came from Satan, who apparently goes "to and fro, in and out of the Earth". Based from these two Gods making a deal on Job's faith, this kind of remind me of the movie "Clash of the Titans", as this scene shows Hades making a deal with Zeus to get the people to worship the gods (Interesting enough, they show Hades in the attire of "fire", "darkness" and "smoke", like the God of fire in the Bible).
Now, this apparent "fire from Heaven", also shows that the dog God called "Xolotl" (Twin deity to Quetzalcoatl), can also do the same thing.
