I watched the whole video and the only thing that the scientists know for sure about the Tunguska explosion is that nobody knows for sure what really happened. The theories include an asteroid, a comet, an exploding UFO, ball lightning, an extraterrestrial nuclear bomb, even a swarm of mosquitos - or some combination of any of those.
So you could almost say that the details of the Tunguska explosion are just as much a mystery as the details of Sodom and Gomorrah.
Here is the passage from Genesis 19: 12-29
12 Then the men said to Lot, “Have you anyone else here? Son-in-law, your sons, your daughters, and whomever you have in the city—take them out of this place! 13 For we will destroy this place, because the outcry against them has grown great before the face of the LORD, and the LORD has sent us to destroy it.”
14 So Lot went out and spoke to his sons-in-law, who had married his daughters, and said, “Get up, get out of this place; for the LORD will destroy this city!” But to his sons-in-law he seemed to be joking.
15 When the morning dawned, the angels urged Lot to hurry, saying, “Arise, take your wife and your two daughters who are here, lest you be consumed in the punishment of the city.” 16 And while he lingered, the men took hold of his hand, his wife’s hand, and the hands of his two daughters, the LORD being merciful to him, and they brought him out and set him outside the city. 17 So it came to pass, when they had brought them outside, that he said, “Escape for your life! Do not look behind you nor stay anywhere in the plain. Escape to the mountains, lest you be destroyed.”
18 Then Lot said to them, “Please, no, my lords! 19 Indeed now, your servant has found favor in your sight, and you have increased your mercy which you have shown me by saving my life; but I cannot escape to the mountains, lest some evil overtake me and I die. 20 See now, this city is near enough to flee to, and it is a little one; please let me escape there (is it not a little one?) and my soul shall live.”
21 And he said to him, “See, I have favored you concerning this thing also, in that I will not overthrow this city for which you have spoken. 22 Hurry, escape there. For I cannot do anything until you arrive there.”
Therefore the name of the city was called Zoar.
23 The sun had risen upon the earth when Lot entered Zoar. 24 Then the LORD rained brimstone and fire on Sodom and Gomorrah, from the LORD out of the heavens. 25 So He overthrew those cities, all the plain, all the inhabitants of the cities, and what grew on the ground.
26 But his wife looked back behind him, and she became a pillar of salt.
27 And Abraham went early in the morning to the place where he had stood before the LORD. 28 Then he looked toward Sodom and Gomorrah, and toward all the land of the plain; and he saw, and behold, the smoke of the land which went up like the smoke of a furnace. 29 And it came to pass, when God destroyed the cities of the plain, that God remembered Abraham, and sent Lot out of the midst of the overthrow, when He overthrew the cities in which Lot had dwelt.
Again, Lot's wife was turned into a pillar of salt when she looked back on the destruction of Sodom and Gomorrah. Are there any reports from the native tribes in the area of people or reindeer being turned into salt? Are there an inordinate amount of salt deposits on the outskirts of the blast zone?
Also, the quote from the angel "For I cannot do anything until you arrive there." So, was the angel going to simply pause the asteroid/meteorite/comet in mid-air until Lot made it to the city that doesn't seem like he originally planned to spare? That (along with shielding this small city from the blast) would require just as much of a miracle as simply sticking with the Bible's description of GOD raining down brimstone and fire on the cities.
I'll say it again, I have no problem with finding natural explanations for the miracles in the Bible, but I do have a problem with twisting or distorting the Biblical accounts to fit our limited understanding of the universe and the laws of physics.
